I don't know how to go about this on your site but there is a song that was originally made by someone else yet I don't know the name of the song or artist. The song today is called "What's going on" by this group called Southside Playaz which was not a popular song, but I heard the original version by some other artist or group and it was beautiful, it was an instrumental with a Kenny G type feel and the only lyrics that were said was, "Bet you don't know what's going on, she don't love you like I do."
