New Taylor Swift music is always a big deal because sure enough, after its release the songs tend to conquer the charts for a long time.
Tay's been teasing a new era - #TS7 - for a couple of months now with a sunny, film-grained, pastel vibe on her Instagram (gone are the dark, bitter Reputation visuals) and last week a countdown started ticking down to today.
Fans understandably started losing their minds but it's all come to a head now - Taylor's first single from her next album is called ME! and it features none other than Panic! At The Disco mastermind Brendon Urie.
They've dropped the song's music video too and it's a pastel wonderland with a billion different technicolour sets and some insane visuals. The song is a classic Taylor pop banger, back to her Red and 1989 era roots.
It's the first time Taylor's collaborated with a band in the pop punk scene in years - back in 2009 Taylor featured as a guest on Boys Like Girls' album Love Drunk - and traditionally the singer doesn't feature many artists on her songs. It all changed in her last album Reputation though, which featured guests Ed Sheeran and Future.
ME! features Brendon heavily though and is a duet in every sense of the word, an interesting move as she leads into her next album.
Bring on #TS7!
