If you have used needle drops - STOP and get legal clearance first.

If you simply recreated the music with your own instruments and performers, see the info in the thread about mechanical licenses (early in the thread) There is also info there about if you used a sampling keyboard with built in samples or some other device that you purchased with built in samples. In those cases where drums or horns or whatever were sampled and you purchased that instrument or module, that's different.

IF you used scratches and samples from RECORDS though - they are copyright protected. STOP before going any further. You can find yourself in more trouble than you can get out of if you don't follow the law
