I have a suggestion for a feature.

Have a batch job run from time to time and compare the the songs bumped between each listener (O n^2 listeners).

Or maybe between each listener and the to 100 listener and sort these listeners by songs bumped in common.

That should make it easier for people to find a user whose 'Radio' one would like to listen for.

Report could be something like:

You: Warmal Songs bumped 130
leaders: Total Bumped Overlap %Overlap
MikeMusic 200 69 34.45
DudeA 1232 75 6.08
..
..

You should be able to sort that report by Overlap and by percent Overlap.

(If you patent this put my name on it :-) )

This reminds me, what happened to the feature request forum?
