Favtape is another new mixtape creation site, but its standout feature is its automation process, which creates a mixtape based off songs you've listened to on Pandora, or those you've favorited on Last.fm. Provide Favtape with your Pandora URL or your Last.fm username, and a mixtape will automatically be created for you with a unique URL that can be accessed anytime.
The mixtape itself consists of 10 songs, which appear to be the most recent from your Pandora or Last.fm activity. For each song on your mixtape, you'll have several options-- play the song, purchase it on iTunes or Amazon, see the lyrics, nab a ringtone (provided by Flycell), share the song, or receive more songs based on the artist or on similar tracks. There's also the ability to see others' mixtapes on the site, with voting options intact so you can see the most popular mixtapes created by other users.
Perhaps the best feature of Favtape is that it takes your streaming music from two popular music recommendation engines and offers a place where you can hear the songs on demand, which is something you can't readily do on Pandora or Last.fm. The downfall to Favtape's particular approach, however, is that its limitation of ten songs acts as a mere snapshot of your account activity on Pandora and Last.fm, and despite the additional options on Favtape, there's not much you can do to turn actions on Favtape directly back into actions within a community network like Last.fm.
The recommendations on Favtape are also a bit erratic--when clicking on Similar Artists for some musicians, I received only 3 song titles from the same artist, and when I clicked "play" to actually hear some of the songs, they turned out to be songs from entirely unrelated artists. Yet clicking on Similar Artists for other musicians, I received 100 recommendations from a variety of singers.
