Purple Rain, Eddie and the Cruisers, 8 Mile?  What's the best music movie of all time?

I'm more than a music and radio junkie.  I'm also addicted to music movies.  As a Prince fan, clearly Purple Rain is my favorite.  What do you think are the Best Music Movies Of All Time?

"Crossroads" with the killer guitar duel between Ralph Macchio and Steve Vai?  "8 Mile" with Michigan's own Eminem?
