Great films where music is a central theme.

Il start light and move on to more contreversial suggestions:

Those already mentioned:
Amadeus (BTW the sound track on vinyl is pretty good too!)
The soloist (so-so, too much digital enhancement for my taste)

Now for a few new ones that come to mind:
Departures (Japanese film that won best foreign film at the 2009 academy awards) The central character is cellist that looses his job. Great music and movie.

Dancer in the dark.
Bjork! and Lars von Trier! Not for everyone, but if you like contemprary electronique music it is great.

My next suggestion is about the music, within the context of the movie, and not an endorsment of the movie itself. Just watch the prologue it's enough (if not too much) Lars Von-Trier's Antichrist. The opening seen features the Aria Lascia Ch'io Pianga, it is emotionally outstanding. Having a young son, the seen really struck a cord and it is no small part due to the music.

On a lighter note, best musical TV episode (no not Glee!) is the Simpson's episode where they go to Italy to chase Side-Show-Bob and end up at la Scala, where Krusty The Clown is performing "I Pagliacci" and finally Side-Show-Bob removes Krusty from the stage just in time to sing "Vesti la Giuba"... The show inside the show inside the show, you gotta love the Simpson's

Wow, after re-reading my post I seem to have a really grim taste in movie and music.

Jax2, true, music is not central to Antichrist.

Here is another suggestion that comes to my as I listen to Swan-lake. Black Swan. It must have been mentioned already...

Let me start with one which has most likely been mentioned already and if it has then shame on you. SpikeLee's
Better Blues.

Then there is Tony Gatlif, who has produced several excellent movies on a variety of themes of gipsy music. My personal favorite is Vengo, A movie about two fueding gipsy familied in Spain. Flamenco puro!

Second is Tony's first film Latcho Drom which recounts the journey of the gipsy culture from east asia to the mediteranean, eastern europe and north africa. The story is told entirely through song, evolving through time and cultures. Beautiful and educational!

Finally on the theme of gipsy music, Roma gipsy in this case,the Serbian movie Black Cat White Cat.

So all this to say, I am not all about gloom and doom. Although mid-week can get depressing. But by Friday evening my mood lighten's up, the wine at dinner helped to!

One last point, I hate this thread! It is urging me to get my TV/Cinema setup going. Ever since we moved, the TV has been split from the Hifi.I get a dedicated room but no screen. That means that movies are watched without proper sound. For most movie I don't care but for the movies mentioned in this thread it is essential for their enjoyment

Mo Better Blues. Fat fingers on the BB
