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.

Mariah Carey, “Bye Bye” [Official]
Carey says E=MC² is a sequel to 2005’s Emancipation of Mimi. We can’t get the acronym to work out, either, but it’s no matter: This E is almost as charming as the last one. Exhibit A: this bright gospel number in which Mimi bids a heartfelt farewell to friends who have left this world and have gone somewhere better.

Frightened Rabbit, “The Modern Leper” [MySpace]
This Scottish quartet describes the delicate art of getting dumped and, in the process, creates one of the year’s best rock records. By the time the whole band comes charging in on the chorus, your whole body will be made of gooseflesh.

Thrice, “Broken Lungs” [MySpace]
This is the final installment in Thrice’s series of concept albums about the four elements. But wait! Come back! The first part might have been a dud, but “Broken Lungs” proves the California group is finding their way back: Coils of guitar expand and contract slowly as Dustin Kensrue’s weatherbeaten tenor voices the great existential questions — where did we come from, where are we going and what possessed us to write concept albums about earth, wind, fire and water?

M83, “Graveyard Girl” [Pitchfork.tv]
An early frontrunner for single of the year, this new wave chestnut by French one-man band M83 is three minutes of raw teenage pain in search of a John Hughes movie. By the time we get to the spoken word passage, where the girl of the title announces, “I’m fifteen years old, and I feel it’s already too late to live,” we’re in the car and halfway to Duckie’s house, tears streaming down our face.

Children of Bodom, “Hellhounds on My Trail” [MySpace]
So, a few quick things you should know about Children of Bodom: they’re Finnish and their name is a reference to a triple murder that took place in the 1960s. Now here’s why you should care anyway: because their music is the perfect fusion of whiplash death metal with art-rock grandiosity. No keyboard has ever sounded as deadly as the ones stabbing their way through this song.
