On the subject of repeats:
Many records end with the chorus repeating into oblivion (they sort of run out of things to say, so they keep repeating the chorus 'til it fades out), but I would like to point out some notable offenders:
Bruce Springsteen, "I'm Going Down." I once heard a dj say that Bruce says "down" 84 times in that one! (Again, difficult to say because it fades out at the end.)
Kool & the Gang, "Fresh." Obviously, a group that went on a binge of one-word titles for their singles after the success of "Celebration, but they were never quite able to capture "lightning in a bottle" again the way that they had done with "Celebration." I listened to "Fresh" while it was a hit, and I believe I counted well over 50 "freshes" in that one! But it's been a while since I've heard it, so it's no longer "fresh" to me.
But I believe the champ when it comes to repetitiveness would have to be Rocky Burnett's "Tired of Toein' the Line." This one even starts out with the chorus! Isn't that a little like eating dessert first? You know that when you must "pad" a song for length by opening with a chorus (a repeating one at that!), that you might want to consider writing another verse for it. I believe the song goes chorus, verse, chorus, solo, chorus to fade, with repeats on each of those choruses. I like the song, and I have the 45 of it, but it's one that I can only take in limited doses because of all the repetition on it!
