Well I'm 36 and long past the "bubble gum pop music" stage.
And hip-hop makes me want to tear my ears off. ; )
CCR, Pink Floyd, Tom Petty, Talking Heads, Robert Plant, Fleetwod Mac, Bowie, Clapton, Peter Gabriel, Jackson Browne, Joe Walsh, ect...
If I'm heading for Corpus Christi out comes the Jimmy Buffet CD....
About as heavy as I ever got was AC/DC back in the day.
I like the 70's and 80's, but am not stuck there. Austin's kinda cool in that we get a lot of "offbeat" music. For modern stuff I like Pete Yorn, Jack Johnson, Spoon, Dave Matthews, Ryan Bingham, Gomez, My Morning Jacket, ect.
And if I'm in a "Texas" mood I pull out Robert Earl Keen, Pat Green, or if I'm driving up to North Texas some Jerry Jeff Walker "Redneck Mother".... and when I leave Texas some of Jerry Jeff's "London Homesick Blues". ; )
