How come not on itunes?

Can't Stop is an UNRELEASED DMB song, it was brand new on the summer tour last year. Go to antsmarching.org or dreamingtree.org to download a show that it was played at last summer. This is perfectly legal cause the band allows taping at their shows and these tapes can be shared and distributed for free (those are the scattered mic stands you see set up close to the stage in the crowd). That is the only way you can get this song until the band releases a new album.
