Not sure what you're trying for here, but if you need to remove some silence between songs, you could use Edit > Cut or control-X?!
If there's a seam there that you then want to heal up, select over it and click control-J to Join, or in the menu, Edit > Clip Boundaries > Join.
If you still hear a discontinuity at the seams, you can try a quick fade out and fade in to clean that up?
