Jazz/blues/R &B reccomendations

I'm trying to get into some older music. So much is forgotten today. Everybody I know seems to listen to angsty "I hate my mom/girlfriend/life" modern rock/new metal. Sometimes I just need to put on Booker T. and the MG's or something classic just to keep me in a good mood, but I keep playing the same stuff over and over. I've listened to some old, old stuff like Fats Waller, Scott Joplin, Blind Blake, Blind Boy Fuller, Rev Gary Davis, Django, etc and 50's-60's R&B a little bit... but not much more than Booker or Al Green and Coltrane..and some other stuff. I'm just trying to keep busy with listening to music. Anybody have any suggestions?
