I need to know the title of this reggae song:

[thunder2821]

I was in Jamaica recently, and while traveling through Ocho Rios or another town from Montego Bay to Beaches Boscobel(I'm pretty sure it was Ocho Rios) I saw this car. It had a left window replaced with what looked like a speaker. It was behind our tour bus and was playing a song and I didn't know what it was, but I REALLY liked it. It was reggae I think and it sounded something like a guy singing "Wah wah wah wah wah" or "yah yah yah yah yah" or something along those lines. If anyone knows the title of the song, I would be really happy. Please help!!!!!

p.s. I checked on the internet and beenie man/ yaw yaw came up but i listened to it and it didnt sound right. if anyone finds it please contact me!!!!!
