Pandora and Last.fm are both services that purport to recommend music to you based on your musical preferences, but in different ways. Pandora lets you pick a song and then recommends song with similar musical qualities. Last.fm, on the other hand, recommends music based on the preferences of other people who like some of the same music you do. Blogger Steve Krause used both Pandora and Last.fm for a few months and wrote a nice article on the services' differences and similarities and how good they really are at recommending music. Ultimately Krause decided that both services are cool, but found "Last.fm better than Pandora at delivering songs that I liked or at least didn't feel compelled to skip."
