VLC is great as a player of just about any music or video format - so now there is an App that allows one to control VLC volume and jump ahead or back in songs or movies - Got your laptop hooked up to the tv to play a movie? Lay back and use your Apple unit as a remote. Easy peasy setup and use. Do need to have VLC loaded on your computer to control it and the latest version works best with the remote App.
Here's one source for download and setup:
