Shared an apartment with a friend in college. He and his girlfriend played Renaissance/Annie Haslam constantly. Over and over and over and over, broken up only by Billy Joel. Just can not listen to them any more, and can only take Billy Joel in very small doses. Do not have either in my library.
On a different note (yes, very poor pun is intentional), I have been in music heaven swapping albums with the guy I told you about. I have added at least 200-250 albums so far, mostly all blues and jazz. He has gotten a similar number from me.
Here are some of my new adds - Beth Hart, Coco Montoya (both on your excellent recommendations), Walter Trout, Sonny Landreth, Eric Gales, Matt Schofield, Gov't Mule, Chris Duarte. I've filled out on these guys - Buddy Guy, Jonny Lang, Tinsley Ellis, Eric Johnson, John Mayall, Kenny Wayne Shepherd.
I'm through all of his jazz, and about 80% through his blues. Won't be buying anything for multiple years as I listen through all of this. He is equally thrilled, filling out his jazz through me.
I get that about listening to someone too much. My best friend loved Billy Joel, he was not a favorite of mine to begin with but hearing him over and over was a bit too much. Plus because he was from Hicksville most local radio played him too much too. I think you should give Renaissance another try.
