Aurovine: Did exactly the same, chatted with their support (through email), but no results.
Audiocoin: traders, only recently traders did pick up this coin, not sure why. Musicoin did pick up pretty well, but I'm personally not very pleased with their change in strategy; from a music/artists coin, to a basic income coin (ok, they may have the artist in mind, but their statements are more generic). Also, I'm not very pleased with their current interface, playlists shall be supported for instance; Or did they enable that by now?
