Alkaline Trio have posted a stream of their upcoming single, "This Addiction," from their highly anticipated seventh album of the same name. There's a catch, however -- one must post an advertisement of sorts on either Facebook or twitter to hear the song. Check it out here.

Slated for a February 23, 2010 release, This Addiction will be the Trio's first album under their own Heart & Skull label, an imprint of Epitaph Records. The band will hit the road for an extensive American tour with Cursive beginning February 16.
