Not only were you not typical, but you're spanning too many eras for all of this to have been in your teens, especially as defined by Arbitron (12-17) .
I've always been eclectic, but even my list isn't that long. If we were to take 1972 and 1973, when I was 16 and 17, I'd listen to KFI for Lohman and Barkley, KMPC for Gary Owens and Johnny Magnus (before he left in spring of '73) and KDAY for Wolfman Jack. Stations that I'd listen to no matter who the jock was was a pretty short list. If I had to put it in order:
KHJ
KKDJ
KROQ-AM
KLOS
KHJ-FM
KMET
In '69 and '70, I listened to KBCA, but they lost me around '71---I just didn't hear as much jazz that I liked and there was more interesting stuff (to me) happening in rock. I listened to KRLA, then, too, but Shadoe's AOR experiment and the knee-jerk to AC in March of '73 didn't work for me, so my listening to them tailed off after '71. And in '69/'70 I listened to KGIL quite a bit---especially after KFI tried being more modern, panicked and hired Dave Garroway for afternoons, but again, after '71 or so, I cared more about rock and didn't really listen to MOR/AC again (apart from Lohman and Barkley, Gary Owens and Johnny Magnus---who was really more a jazz dj) until I started programming it in '75.
KHJ-FM lost me with the flip to KRTH because they focused on 1955-63 music, which was just too old for me at the time. Still is, really.
I'd argue that I was more open than most of my peers (maybe because by '72/'73 I was in radio myself). The guys I knew who liked KLOS and KMET wouldn't be caught dead listening to KHJ or KKDJ and most of the girls I knew were the exact opposite---KLOS and KMET rocked a bit too hard.
