I love going to iTunes and downloading all the free music for the week.

Sometimes I delete the music immediately because it doesn't sound very good to me. Sometimes I keep the music forever. Sometimes they have really good music that is free that week. Occasionally there will be a really good one.

Most of the time they are just artists that want to get themselves out there. They usually aren't all that great. I usually end up deleting them. There's nothing wrong with getting the free music at first and then deleting it if it isn't something you are really interested in.
