At last week's Superbowl Halftime show, Prince opted to cover the recent Foo Fighters track "Best of You" and the result has been much speculation from media source and the band themselves.

Oddly enough, the Foo Fighters had originally covered Prince's "Darling Nikki" which had evoked some complaints from Prince:

Prince was less than pleased, telling Entertainment Weekly that he didn't appreciate the Foos (or anyone else) covering his work, and that Grohl and company should "write [their] own tunes."

Drummer Taylor Hawkins, quoted at both MTV and Rolling Stone contend that this was some sort of strange payback for the original cover - which Prince prevented the release of in North America:

Dude, I have no idea why he did it, but I'd love to find out, I mean, the thought went through my head that maybe he was doing it as a sort of 'F--- you' to us, or maybe he really likes the song. Either way, it was pretty amazing to have a guy like Prince covering one of our songs -- and actually doing it better than we did."

The Foo Fighters are working on their next album and are apparently considering another Prince cover, just to rankle the famous singer:

We're just getting started on a new album, just demoing and stuff right now,But maybe we'll get cracking on a version of 'Purple Rain' to see if maybe he'll hate it even more.
