Instead of hitting Search six times to search by source or 5 to search by genre, why not have it like this:

Search then "2" search by artist
Search then "3" search by source
etc... i.e. it should use the numbered buttons as they are currently used for the "more from this.." or "hate this.." features. I realize numbers are also used to type in the search criteria, but it's much less of a pain to hit "search" "2" and then type in an artist than it is to hit Search EXACTLY four times. Especially when using the remote in the car and you're not sure the player is going to receive the code. It would require a lot less looking at the display and a lot less button presses.

Since there's no # for "PIN" currently I guess it could use 1. So "search" "1" '1234" or something.

This might have been suggested before but I think it would be a real improvement. My brain is programmed like "artist=2" "year=6" etc. Why not put that to good use...
