I know Rihanna releases new singles more often than she changes her socks, but this one is actually amazing. It's the first single from her as yet untitled new album (!), which is released November 21st.
Crucially, the new track features Calvin Harris, and it's as brilliant as you'd expect a collaboration from these two to be. Capital FM premiered the track here in the UK earlier today, and they're about to play it again just after 3pm (they really are milking it). Tune in if you haven't already heard it.
UPDATED: Even though Capital are playing it every ten minutes or something ridiculous, you can listen to it here now if you wish.
