I run the whole gamut, except for country.
I'll listen to stuff from the 30's, early Jazz, early Christmas music, 70's, 80's 90's, 21st Century, old-school rap, new school rap, gangsta rap, local bands, etc. My Pandora playlist probably confuses people!!
My only no-goes are Country/Western (unless it's Merle Haggard, Johnny Cash, Waylon Jennings, etc) 50's and 60's pop music and modern music that is obviously a re-hash of recent hits/styles.
I am also firmly against anything using AutoTune. That's a big "heck-no" from me.
My most heavy rotation of the last year has been Puscifer, Primus, RUSH, and many 80's rock bands like GNR, Cinderella, Motley Crue, etc. Then I'll switch it up to Da baby, Trinidad james or Danny Brown to let the 2 15's in my vehicle flex a bit. Maybe even some DJ Russticals for maximum flex.
I think my musical randomness may be indicative of some mental health issues!
