There are four licenses I know of. I know because of Warner Chappell Music's licensing, but BMG only lists one and because I have never purchased with them, I can't tell you which.
Here are the four licenses as proof on a song:

Here is the list of four:
Master - A master license gives the license holder the right to use a recorded piece of music in a media project such a film, TV show, commercial or another visual creation or audio project.
Mechanical - A mechanical license gives the license holder the rights to reproduce and distribute copyrighted musical compositions (songs).
Print - A print license gives the license holder the permission to print the sheet music, notes, or lyrics of a song that someone else wrote.
Sync - A music synchronization license is a music license granted by the holder of the copyright of a particular composition, allowing the licensee to synchronize ("sync") music with some kind of visual media output.
Hope this helps. And I think BMG would tell you what license you have purchased.
