How do people come across new artists that they like? Do you hear them on the radio? Get told about them by friends? Have iTunes recommend them as "similar to what you listen to"?
I have 13,000 songs in iTunes and even so I tend to listen to my "favorites" in my playlists a lot. I don't even listen to all the CDs I own already. So it's intriguing to think about going out and somehow "looking" for new music.
