I'm sure this has been addressed but I cant locate it - in iTunes, I have created a few playlists that have a "musical note" icon - there are also several playlists with a "star" icon, I guess you could say...What is the difference between the 2? I also noticed that a recent playlist I created contains the artists name and a few songs. On the Ipod, that artist appears in "Playlists" but not under artists...why?
