How Do I Stop A Song From Playing
 

and just skip to my next selection of choice?

Sure just hit the skip buttons at the end or beginning of song. To skip to next song then press the skip to end button at the end of the media players controls. There might be a small pause whilst it changes over to the next song. BUT this is only true with the playlist. If you play a song from the library then it will be treated as a song & on its own so there is no song after. lol :D
