Every Tuesday Single Minded highlights new tracks hitting stores (or the Web) this week. On Fridays, come back for rarities, remixes, mash-ups and more.

Angels & Airwaves, “Sirens” [MySpace]
Second record from ex-blink-182 frontman Tom DeLonge proves the sad truth that growing up means funtime is over. Apparently the answer to the question “What’s my age again?” is “Old, man. Old.”

Jay-Z, American Gangster [Full Album Stream]
Jay recorded this album in two weeks after being inspired by the Ridley Scott film of the same name. Imagine what might have happened if the 3:20 Bee Movie hadn’t been sold out?

Chris Brown, Exclusive [Full Album Stream]
And speaking of old: for his eighteenth birthday, Chris Brown gets the aggressive adulation of teenage girls, a number one single with cyborg hook machine T-Pain and an album that will undoubtedly debut next to Jay-Z at the top of the charts. When we turned eighteen, we got new sneakers and a CD player in our car. So, basically the same thing.

Little Big Town, “I’m With the Band” [MySpace]
Nashville Christian country group turns in an oaky little number that offers a behind-the-scenes of their life on the road. Before you start salivating, re-read the first part of this entry.

Dillinger Escape Plan, Ire Works [Full Album Stream]
This album’s opening track is called “Fix Your Face,” which is precisely what you’re going to have to do after its first thirty seconds. Good God, it’s stunning. If someone could synchronize a workout regimen to this, we could all eat Wendy’s Baconators every meal for the rest of our lives.
