Genre-crossing musical collaborations

::: Friday January 20th :::
A little fun for a Friday: We're interested in artists that go outside of the box... stray from their normal sound and try something new. It's always nice to have a guide when trying something new, so that's what we want. Songs that feature genre crossing collaborations. Two acts that are from different styles of music, hooking up to create a great song. Send in your favorites for today's Daily Feedback.
