Known for his tongue-in-cheek tunes and celebrity mates, comedy rapper Lil Dicky has combined both for a good cause, Earth Day, and created the collaboration to end all collaborations, featuring nearly 30 A-list musicians in a charity song called Earth.

Does Diplo ever stop working? Between working on solo stuff, tunes with Major Lazer, Jack Ü with Skrillex and Silk City with Mark Ronson, it's a miracle the producer has any time left at all.

It's going to be a very busy year for Sia next year as she's announced she's got plenty of new material on the way.

In 2019, Sia will drop her full-length musical Music starring Maddie Ziegler and Kate Hudson plus drop a new record.

Charli XCX just finished part two of her Pop2 shows, bringing a guest-packed show to New York.

Charli XCX will perform her second mixtape of last year Pop2 in its entirety in New York.

Last year, she put on a few very special Number 1 Angel mixtape shows in the US and Europe but this Pop2 show looks to be even more special.

Charli XCX tore down Allianz Stadium as one of the support acts for Sia's Sydney show.

Last night, Cashmere Cat decided to treat his Melbourne show to something extra special for his birthday bringing out Charli XCX and Mø.

The pair are in Australia as they're supporting Sia on her Aussie tour but they stormed the stage with Cashy Cat as their first Aussie appearance on this visit.
