Just found this site, love it!
Okay, heard this song yesterday so it must be in rotation on commercial radio. Suave male voice singing a lot of "nah nah nah nah" but also with the word "right" or "maybe right." That's all the lyrics I could understand. Singer might be black and the music sounded real retro and loungy and funky. But I think it must be a recent release not an old classic song.
Plus it is not this song --> summerlove David Tavare
Many thanks,
