Does anyone have an mp3 of the X-ROCK 80 shotgun jingle
in the clear? Now that's a collector's item.
Earlier it was stated X-ROCK 80 speeded up the music by 3%.
45 (rpm) X 3% = 1.35, or 46.35 rpm on the TT when the songs
were dubbed to cart?
A number of AM Top 40s did run the tables 46 or 47 rpm, which
was done to make the competitor sound "sluggish." The topper
may have been KCBQ San Diego, which according to legend,
ran at 48 rpm.
Pitching up music just doesn't sound good on FM, or at least from
what I recall hearing in the early 90s in Phoenix. Incumbent oldies
KOOL-FM (who didn't go all Xmas back then :

) was challenged by
newcomer KPSN(FM) and at one point KOOL pitched up their CD
players a bit. Sounded terrible. Can't remember what the overplayed
oldie
du jour was back then, but I wouldn't be surprised if it was
Brown Eyed Girl. ;D
