Big Fucking Star

So have you heard of the Covers Project website? It's got to be one of the coolest things ever invented. For music geeks, anyway.
Type in a band name, or a song name and you'll get a comprehensive, user-fed list of covers performed by that band, and what's best, all bands that covered songs from them and which ones.
It's a great way to meet bands possibly influenced by other bands you like. Try typing Big Star and you'll see names like Superdrag, Jeff Buckley, Evan Dando and Elliott Smith.
Of course, the fact that the list is user-kept is also a disavantage, given that some people tend to just throw in whatever they think they have heard, without even confirming, producing certain oddities.
But that doesn't make it less cool finding out that Faith No More has covered Britney Spears.
