[Dixielandjazz] OKUM for an ipod?

[FOThree at aol.com]

Are there any net locations where one can download classic jazz and swing  
era music for to an ipod?  For instance, It would be nice  if I could download 
all of Ellington or Goodman.  Pay sites would be  fine.  How about the entire 
Brunswick or Victor catalogues from the 20's  and 30's.  How long are we away 
from being able to do this?  I'm  running out of shelf space.
