Well...
It was okay, good flow and beat and whatnot, but it doesn't use its full potential. You say it's just a test, so okay, but if you ever decide to redo it, just don't leave the beat running solo for so long. Maybe add some rapping, or sample something. I suggest Juicy (Notorious BIG). The following would sound good in this song I think...
"It was all a dream, I used to read WordUp magazine. Salt 'n' Pepa and Heavy D up in the limousine..."
And however much else you'd want to put it in. Either way, send me a message when you redo it. I want to hear it :)
