What are the names of some popular spanish songs? (older songs, not new)?

By that I mean like cumbia, merengue, and similar music. But there's a song in particular I want to know the name of. I don't know any of the words but I know its an older song with a cumbia beat. They always play it at quinceñeras and such parties but I never knew the name of it. I tried putting in some lyrics of the song on Google but almost every song has the same words in it. All i know is that's it's an older Cumbia song and some of the words are:

aaaah

por que (or con quien) lloras

like I said that could be any song. But if you could please help me name this song that would be greatly appreciated.

Thanks!
