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.

Nikki Sixx, “Life is Beautiful” [Heroin Diaires MySpace]
Mötley Crüe bassist documents destructive power of heroin in a song that recalls Papa Roach — making it the first anti-drug single to ever inspire drug use.

Cartel, “Lose It” [Cartel's Official Site]
Recorded while the band was locked in a bubble, cruelly cut off from the rest of the world. Unlike every other emo band, who just think they are.

M.I.A, “Boyz” [M.I.A. Official Site]
Every so often, the blogs get one right. Also, boasts visual effects by Strong Bad.

Rilo Kiley, “Silver Lining” [Rilo Kiley MySpace]
Finally, a new Dido single!

Swizz Beatz feat. Coldplay, “Part of the Plan” [Swizz Beatz MySpace]
Further proof that the caliber of rock/rap collaborations has dipped precipitously. Hot Tip: We hear Chris DeBurgh isn’t doing a whole lot these days.
