I'm looking for some advice. I'm looking to buy a hard drive based MP3 player - preferably 80 gigs. I have looked at the iPod and Zune, however both do not seem to offer a feature I'm looking for. What I'm looking for is the ability to have a "Now Playing" playlist running. For example I'll pick a song to play (not using a play list at this time), then as I navigate around I can add songs at my choosing. I know Apple has an On the Go playlist, but this isn't what I'm looking for. Something like Winamp's Enqueue, or Microsoft Media Player's Add to Now Playing. Does any MP3 player have this feature?
