There's a feature I've been wanting for a while in an MP3 player. It's pretty simple, but to the best of my knowledge nobody has implemented it. Basically, I like to put my music on shuffle so I'm not listening to the same few albums/artists all the time. But sometimes it will get to a song I haven't heard in a while and I remember the album/artist and want to hear more of that. I want to jump out of the shuffle and to the full album that this song is from, or to more songs by this artist. And I want to be able to then return to the shuffle, after hearing the album/artist.
It doesn't seem like it would be too hard to implement, and I think it would be a really cool feature. Of course I can currently hear a song and decide to go the album myself. But this involves several steps and it means I lose the current shuffle I am going through. With this proposed way, you could jump out and then back into the shuffle so you wouldn't hear all the stuff you had already heard again. That way you could go through the whole shuffle and hear everything you have once. So there's my 2 cents.
