A couple of longer songs I've been listening to today:

Heroin & Rock N Roll from Lou Reed Rock & Roll Animal

All hail the wizard!

English Dogs - Brainstorm

Though I've already been labeled a 'Street Team member' for them in the couple of hours that I've been on this forum, I won't hesitate in putting forward Crossfade's "Make Me A Believer" as it's just over 10 minutes long (if memory serves me correctly).

"Rain When I Die" and "Rooster" by Alice In Chains are the only other ones that I can think of.
