The music is beyond frustrating and I can only assume this is deliberate. On my phone, if I search for music that I own and have downloaded, it still returns results from the store/streaming and not the specific song/artist I asked for. I'm looking for something else to manage mp3's again, preferably with an easy way to backup storage -- and it shouldn't be a monthly service.
