I listen to music every day, although often I am doing something else. I tend to listen to rock in the am (getting ready for work, driving in) and jazz in the evening (cooking dinner, reading before bed, etc.).
As for which artist, I tend to go in "subgenre spurts". I may be into the organ thing for 2-3 months, then I move on to more avant garde stuff and then maybe some 70s fusion-y stuff. I have wondered if there is any linkage between subgenre and my overall mood, stress level, etc. So far, no discernable connections! I will sometimes "go exclusive" to either rock of jazz, but usually I am listening to both over the course of a few days.
I really do apreciate the size and diversity of my jazz colection - there is always something perfect to listen to.
This board definitely is a stimulant for particular artists. Case in point - recently there were some lukewarm comments about Freddie Hubbard's Blue Note records. I happen to love most of this work, but haven't listened to it hard core in maybe 15 years. So I have been pulling them out over the past few weeks and it has been a blast to reconnect with these old "friends"
