The latest MP3s to hit the blogs.

1. Smashing Pumpkins, "Doomsday Clock"
For Billy Corgan's sake, let's hope doomsday arrives before he sees the reviews for the Pumpkins' new album. [Matt's LiveJournal]

2. Aerosmith feat. Sierra Leone's Refugee All-Stars, "Give Peace a Chance" (John Lennon cover)
Unfortunately, none of the proceeds from the new John Lennon charity tribute album will benefit the victims of Steven Tyler's rapping on this ill-advised cover. [Ingrained Refrains]

3. Annuals, "Swing Low, Sweet Chariot" (traditional)
Amazingly, this North Carolina sextet can make any song — even this spiritual that was composed in 1862 — sound like a track from the Flaming Lips' The Soft Bulletin. [I Guess I'm Floating]

4. The Thrills, "Long Forgotten Song"
The name of this new song from the Dublin quintet suggests any number of easy punch lines, but it's actually pretty catchy. [Fuel Friends]

5. St. Vincent, "Marry Me"
On her first solo album, this sometimes guitarist for Sufjan Stevens and the Polyphonic Spree manages the rare feat of sounding both feisty and Feist-y. [Dead Indie Elephants]
—Lane Brown
