Hardly as obscure or super-edgy as most of the acts here mentioned, but I just wanted to say that Bandcamp is also the only legit place to get FLACs of the b-sides of Courtney Barnett's "Pedestrian At Best" and "Kim's Caravan" singles (which don't come with any download codes):
B-side: The Lemonheads' "Being Around"
B-side: John Cale's "Close Watch"
