Playmode: Jump in <seek> Next Song, and Jump out <before end> current Song!

What why?
if i play club-music or Techno, then there are a minute or longer intro-Sounds, and at end again, thats nice for DJs to mix to next Song!
it will be nice, to enable a play mode to skip this part of songs!
its could be a feature, to hear only a one ore two minute snippet from a track, that make it easier to hear over multiple songs for rating!

cue files could be a answer, but i dont have tested, was only a idea
