If you have itunes (which i'm sure you do) Update and turn your Genius on.I always had problems picking my tunes for the day not really feeling like adding playlists before hand, not really knowing what i wanted to listen too or always getting the ipod out to pick more tunes. Was never ever happy with just shuffling through.
I just pick 5 different songs i'm into on that day, let my genius pick 100 tunes of the same Genre for each song and what not, 95% of the time, every song on the playlist is something i would never skip through.
You kinda have to have a decent sized music library or chances are it'll pick whole albums and mix em up.
Give it a try, i have faith in it.
Other than that Pandora.
