Wow. Big site, with scads of independent albums. They make it dangerously easy to wander around, browse, find stuff that's like what you want (including a somewhat offbeat collection of musical "flavors" and a strong "sounds like" feature), listen to selected tracks off of albums (full two-minute excerpts, rather than the puny 30 seconds I get with iTunes), and then buy them. I wound up buying four albums by people I've never heard of before (found through random wanderings), plus an Ookla the Mok disc.
I have a nasty feeling that these people are going to wound my wallet rather deeply...
