it is rico
Dwight Yoakam
It was sang by Fyfe Dangerfield and Billy Joel and you can by it on itunes.
It is a country music song. SEE: http://en.wikipedia.org/wiki/Achy_Breaky_Heart
The only person I know of that is named Billy that sang country music as a kid is Billy Gilman, but he was born in 1988 so it would have been 2002 when he turned 14. I'm confident, though, that this is who you were thinking of.
