We'll send you an email indicating specifically which song had it's copyright claimed and we'll take it down from stores until this issue is solved.
If the song is really yours, you must send us proof of ownership or else it'll be permanently taken down from stores.
But this is more likely to happen when you upload a song with us that is already online through another distributor. It also happens if your song is online on a free platform like SoundCloud. Please make sure to contact your previous distributor to take your song(s) down from stores and make sure it's not online anywhere else. Once you upload your song with us again it'll be delivered and accepted on stores.
