I have recently had tracks show up on tunesat for the History Channel. The publisher for these tracks has not registered these tracks and it is my understanding that I will still be able to get paid back end royalties. What I was wondering, is if there is a way to look up cue sheets for songs that are not registered on the ascap site. Also is it a bad idea to go ahead and register the tracks myself in order to see the cue sheets? Or will that mess things up? I am somewhat new to this business and would greatly appreciate any suggestions or comments. Thanks
