2020's been one hell of a year, but it also meant artists found new ways to collaborate. While a lot of them weren't able to get in the studio together, they were able to make magic happen thanks to the Internet. In many ways, music changed forever in 2020, and we expect to see a lot more big names collaborating in the future.

We've taken a look at some of the biggest and best collaborations that dropped this year, and what made them so special. It's always exciting when two or more of our favourite artists decide to jump on the same track together - it's the crossover event that you never knew you needed.

Cardi B & Megan Thee Stallion - WAP

When Cardi B linked up with Megan Thee Stallion for WAP, the world stopped and took notice. It's the biggest song of the year, thanks in part to the stunning music video that dropped alongside the track. Everything about the release of WAP was on point, and it turned into a genuine pop culture moment.

Both Cardi and Megan aren't afraid to get raunchy on the track, and it became a sex-positive anthem that annoyed a lot of conservatives, while exciting everyone else. The world was waiting for Cardi and Megan to work together, and when they finally did, it blew us all away. 

S1mba & DTG - Rover

UK rapper S1mba didn't just write his smash hit Rover, but he produced the track as well. Originally released in November 2019, the track went viral on TikTok in early 2020, which is yet another example of social media giving a song a second life.

The track, which features fellow British rapper DTG, sees S1mba talking about how he'd rather make money than fall in love. After all, as soon as he started doing well for himself, people started paying attention.

The track spawned countless remixes, including one featuring Australia's Hooligan Hefs, Hooks and Youngn Lipz. The track still gets us moving every time we hear it, and we don't think that's going to stop any time soon.

Rico Nasty & 100 gecs - IPHONE

It's hard to pick our favourite Rico Nasty & 100 gecs collab from this year, because the two artists had some serious chemistry going on throughout 2020. However, Rico's IPHONE has to take the cake.

The track, which comes off her huge debut album Nightmare Vacation, was produced by 100 gecs, and it sees Rico turn into an honourary gec. 100 gecs produced other tracks on Nightmare Vacation, but it's this one that captures the absolute chaotic energy that reigns supreme every time either of these artists step into the studio.

Dua Lipa, The Blessed Madonna, Missy Elliott and Madonna - Levitating (Remix)

How do you follow up one of the year's biggest albums? If you're Dua Lipa, you get on the phone to The Blessed Madonna, Missy Elliott and Madonna to jump on the remix for her track Levitating.

Dua doesn't appear overawed in the presence of two of her "idols", but instead they all raise each other to another level. The track appears on the remix album Club Future Nostalgia, and it's perfect for the nightclubs of the future - but at the same time, it'll get you dancing right now. Dua truly made 2020 her year.

OneFour & The Kid Laroi - My City

If you had to pick the two biggest hip-hop artists in Australia right now, you'd be hard-pressed to go past OneFour & The Kid Laroi. They both became global superstars in 2020 - which is why this track is so fitting.

My City sees both OneFour and Laroi talking about how they've become the kings of Sydney, with Laroi self-proclaiming that he's the "Drake of my city". It's hard to argue with the claim, just as it's hard to argue when OneFour member Spenny says the group "Put Aus' on the map and they all complain". 2020 will be remembered as the year hip-hop in Australia went global - and it's thanks in part to these two artists.

Megan Thee Stallion & Beyoncé - Savage (Remix)

Megan Thee Stallion & Beyoncé are two of Houston's biggest artists, but given Bey's reticence to collaborate with her own sister, it was a welcome surprise to see Bey jump on Megan's Suga track Savage.

However, rather than a tacked on verse, Bey and Megan completely flipped the script on Savage (Remix), and it includes Bey rapping, who sounds like she's having one hell of a time. The track's proceeds went to support COVID-19 relief in Houston, so it was all for a good cause. Can we please get an album full of Beyoncé's bars one day?

Halsey & Marshmello - Be Kind

Marshmello & Halsey's single Be Kind was just the burst of positivity that the world needed in the middle of 2020. It's an emotional EDM track that sees the pair talking about how it's OK to be vulnerable, and how you need to trust the person you love.

The video for the track sees Halsey dancing around a large room, as she attempts to get in touch with Marshmello. Halsey's got some serious moves, and we're not afraid to admit we tried to emulate her while dancing around our living room!

Lil Uzi Vert & Future - That's It 

Lil Uzi Vert has had a huge 2020, and what better way to finish it then to work with Future to drop a whole collaborative album?

The pair have been talking about working together for a while now, and when they released the album, titled Pluto x Baby Pluto, the wait proved to be well worth it. The album's highlight is the track That's It, which really is out of this world. The pair bounce off each other and take inspiration from the other's style - and the real winners are fans of both artists.

Taylor Swift & Bon Iver - exile

Taylor Swift decided to release two huge albums in 2020, folklore and evermore, and the biggest moment of them all was when she called on Bon Iver to feature on exile. The song is a look into what happens when two exes see each other after a break-up, and the feelings that follow.

Bon Iver sings about his dismay at the fact his ex moved on so quickly, while Taylor sings about how the relationship wasn't going anywhere, and the signs that were present. Bon Iver's gruffness contrasts with the silkiness of Taylor's voice - and if you're not welling up by the end of the track, we're not sure you're listening closely enough.

Pop Smoke & Lil Tjay - Mood Swings 

The world lost one of the next generation of superstars when Pop Smoke passed away in early 2020, and the rest of the year was a reminder of just how much talent he had. The posthumous album, Shoot For The Stars, Aim For The Moon, shows where Pop's sound was heading and just how versatile he was.

He worked with Lil Tjay in the past, but their tender collab Mood Swings is an ode to Pop's lover, and proves that he had a more sensitive side. As Pop says at the start of the track "Oh, you ain't know I could sing?" Pop's aim was to keep everything balanced music-wise - and this track is proof of that vision.
