So whats your favorite music themed movie?


I am talking fiction or non, from Almost Famous, Spinal Tap to The Song remains the same........if its about music in any form lets hear your pics, some may learn of a new flick to watch. Cheers

One of my favorites is "A Knight's Tale" (2001) which is a fun mash up of a feel good medieval knight tale with a classic rock sound track. 
Not sure it has been cited, but, Fantasia!!!!!

And Hard Days Night, as already mentioned lots -- revolutionary,. And hosts of Nat Fleisher cartoons from the 30s.

Lots of other good stuff mentioned that I noticed.  But these are genuinely music focused, not just musically valuable for some reason.
