'Twilight: Eclipse' soundtrack revealed, very, very, very slowly

UPDATE 6 p.m. ET: And finally, the seven-hour reveal is over. The full track list is now after the jump.

It's a big week for "Twilight" fans: Tickets for the third movie, "Eclipse," go on sale Thursday (May 13), and while you're waiting for that, you can discover who's on the movie's soundtrack Wednesday (May 12).

And since the revelation of the soundtrack listing has been turned into an all-day affair, that will kill a good amount of the time before tickets go on sale.

Yes, we said all-day affair. Summit Entertainment, Atlantic Records and MySpace Music are dragging out the soundtrack news over a full day, adding one track to the list every half-hour. The slog began at 11 a.m. ET Wednesday.

The track list is after the jump; we'll keep updating throughout the day as bands that will join Muse on the soundtrack are announced.

The track list -- MySpace isn't revealing the list in numerical order, hence the gaps:

1. Metric - "Eclipse (All Yours)"
2. Muse - "Neutron Star Explosion (Love Is Forever)"
3. The Bravery - "Ours"
4. Florence + The Machine - "Heavy in Your Arms"
5. Sia - "My Love"
6. Fanfarlo - "Atlas"
7. The Black Keys - "Chop and Change"
8. The Dead Weather - "Rolling in on a Burning Tire"
9. Beck and Bat For Lashes - "Let's Get Lost"
10. Vampire Weekend - "Jonathan Low"
11. UNKLE - "With You in My Head" (featuring the Black Angels)
12. Eastern Conference Champions - "A Million Miles an Hour"
13. Band of Horses - "Life on Earth"
14. Cee-Lo Green - "What Part of Forever"
15. Howard Shore - "Jacob's Theme"
