Hay que vs. Ay, qué
I was listening to this song called "Grosero" and the first line in the song sounds like "Hay que grosero." The translation of this didn't make much sense to me, so I looked up the lyrics but every site read "Hay que grosero." Is it possible that she's saying "Ay, qué grosero" or does "hay que grosero" mean something? Here is a link to the full lyrics if it helps.

¡Ay, qué grosero! is the right answer. It means "Oh, how rude". Hay que grosero does not make sense.
You can say: Hay hombres que son groseros. But that's a totally different construction.
"Hay que" is a very common structure but in completely different contexts, ie: "Hay que pagar la cuenta" ...... "the bill must be paid" and has nothing to do with the explanitive expression "Ay qué ...."
You have come across one of many internet misspellings.
Hay is a conjugation of haber, the way you put it here, hay que, is an impersonal construction that denotes duty or need of doing something:
Hay que tomar agua después de ejercitarse
Habrá que esperar hasta mañana para saber.
Había que actuar rápidamente para evitarlo.
Ay is an interjection, it is used very broadly
hay que
deber que
y
tener que
casi lo mismo
you must do it, have to do it
