I recorded a song with a producer back in October of 2012. I wrote all lyrics & melody. The producer was contracted to produce the song for me to perform for a Halloween event. He was paid to do song. In December of 2012 I signed with the producers record label. He has now released the song on his own album, without my knowledge, I found out on Facebook when I saw the iTunes link. The song was said to be copyrighted & was not, song is not registered with ascap or bmi, the song is not listed with any credit to me, not even as performer. It's being sold, no payment/royalties to me & I haven't even seen any statements as to how much has been sold. I want to rerecord the song a different way & publish myself as I will be out the contract soon. Will I be able to do so, copyright it, etc, with no problems? I should still be owner of song right?
