I agree! I adore kids singing, but some songs are so relentless in repeating the same lines that it can make a person crazy.
I remember singing it as a kid, and only remember a couple of other lines.
I love Madonna songs, or any songs that take me back to the 80's.
It would be strange to hear so many on the radio though, to me, too. Usually there is a good variety on the radio. I miss living where we actually had radio stations, and stations for whatever mood you may be in.
