Some time back, I bought/sold on Discogs in the 12" vinyl category (music_mike) from thrift store finds. I was able to throw together a Cordova app within a day to price stuff while I was out, and their API is simply fantastic. The database is the total accumulation of literal decades of work with almost nothing thrown away, so it's not the cleanest to navigate for a newbie, but it is deep. Thank you, Discogs!
