This news seems to have hit a couple of stations in the last 24 hours, originally miss-reported as Blink-182 writing a track for Revenge of the Fallen. Blink-182 drummer is a twitterer, and he did tweet:
Listening to a new version of a track I’m playing on for Busta Rhymes for the Transformers 2 soundtrack. Shit is jammin’.
Not hugely newsworthy, we should get the film’s full soundtrack track listing shortly, possibly in April.
