Unless you are, say, a critic at Spin and you spend every waking hour trolling the internet for the next big band, chances are your iTunes library gets a little played out once in a while. Enter One Track Mind, the antidote to stale music collections everywhere in the form of free mp3s delivered daily to your in-box.

You should think of OTM founder Danny de Zayas as your own personal music geek, someone who wonks out on music so you don’t have to. (Case in point: When we asked him what high-profile bands we could expect to see on the site in the next couple weeks, he rattled off names like Rogue Wave, The Album Leaf, Aloha and Radar Brothers—not exactly “high-profile” in our book.) But Danny’s taste is spot-on, and getting under-the-radar singles now is an obvious investment in your future music cred. So sign up for the daily downloads, poke around in the archives and indulge in the extra features (a special four-track post every Sunday, Zip-file downloads of each month’s music and a regular podcast featuring songs, commentary, and discussions with musicians). Just be sure to play it cool when you drop to your friends how much you’re digging the new Seabear single.
