Will there be a way for the user to reset those counters should he for whatever reason decide he wanted to start out with a clean slate?

I hadn't thought about it -- is that really useful?

Say, for instance, if somebody bought a used empeg?

Delete the other guy's songs and upload some of their own?

Or if he got tired of always hearing songs he hadn't heard in a long time and wanted to hear some of the songs he liked that were always low in the priority list because he played them a lot?

Completely random shuffle isn't going away. Biased shuffle will probably be the default, but you'll be able to choose (from the player menus) completely random shuffle as an alternative.

If you really wanted to wipe the slate clean you could delete the songs and re-upload them?
