I like the Empeg over the Riot (don't have and Ipod) because of how I listen to music. I like to play my 2500 songs (all singles) at random. Then when I hear an artist I'm in the mood for I press the "Aritist" buton on the remote and enqueue the rest of their music.

Riot does not do this and Ipod (from the descriptions) apparently doesn't either.

I may buy pearl just for this feature. If it has it (anyone listening)…..
