We’ve got a riddle for you: What do you get when you combine Taylor Swift with an adorable English singer? No, not Haylor – “Everything Has Changed,” her duet with Ed Sheeran. This one makes our list of the top five collabs of 2012. Click below to find out what other songs made the cut.

3. “Everything Has Changed” – Taylor Swift featuring Ed Sheeran

This song hasn’t been released as a single (yet), but we totally fell for it the first time we listened to Tay’s new album, Red. The song combines the talents of two of the best songwriters in pop music today, Taylor and Ed.

2. “Good Time” – Owl City featuring Carly Rae Jepsen

Carly Rae Jepsen followed up her mega-hit “Call Me Maybe” with a cool duet with Owl City. The song was a great summer anthem and the video makes us miss the warmer days.

1. “Beauty and a Beat” – Justin Bieber featuring Nicki Minaj

Talk about epic videos! Justin’s video for “Beauty and a Beat” has to top the list for 2012. Justin staged an elaborate prank on the world with the release of his “Beauty and a Beat” video, which he directed himself. Plus, Nicki’s verse of rap is amazing (we love the part where she references “Selener”).
