We recently came to the realization that any time you upload an mp3 to reverbnation that is larger than 128k, it slams the file down to 128k. That sucks. But what's worse is that your music goes through destructive mp3 compression twice! If you upload a 127k file it won't get REcompressed and it will in fact sound better than if you had uploaded a 256k file! RN sucks balls!
