I think I want something more like the original poster suggested...

So many times over the last few days, the empeg has gotten to a song by some artist, and I think "Oh! I want to hear this other song by them", but can't easily get there. If I could hit something to "stick with this artist" or whatever, that would rule. Then maybe have a way to go back.

Kind of like the button on a TV remote that lets you switch between the last 2 channels... While listening, hit it to switch to THIS artist, then hit again to go back to the previous playlist.
