Which actor would you say could play (instert musician here) in a biopic?

[Lenny Magic]

Okay as the title says which actor could use the amazing powers of actings to portray a famous/not-s'famous musician in a biopic of their life.

(or if you want, which musician would be able to protray a famous/semi-famous actor in a biopic of their life)

They could look very much alike, they could sound the same, whatever so long as you can give some sort of explanation to back up you choice.

Example:

I have always thought Jamie Bell looks quite a lot like Matt Bellamy from the band MUSE. So in a way that could work.

Geoffrey Rush could probably do Geddy Lee with the right hair/facial hair. Although he, along with the rest of the world, has no hope of equalling his awesomeness with a bass.

Probably John Corbett might get away with playing Kurt Kobain. And Angelina Jolie could play a messed-up Courtney Love.
