So anyways
Just so you know, you cannot use ANYTHING that is not yours in your song, such as the a cappella you used. Not just because you've made a legal claim that everything in this song is yours, and it clearly is not, but because doing things like that can cause Newgrounds to get in trouble (ie sued). That just doesn't seem fair to Tom.
Regardless, Im going to review the song now. Overall, it is mastered rather well, but, it seem like the lyrics are a little loud in the mix. It could use some more variety in the background, but as it is, its not bad.
I like some of the rhythmic effects applied in the backgrounds, and i disagree with the guy below, because it sounds to me like the vocals match up quite nicely with the beat.
My suggestion is that from now on, you should try and get people to do original rap for you. There are some pretty good rappers on NG (warspawn being one that I know of). As a bonus, it will be both amazing, and original, and trust me, you'll be much prouder of the result.
Good Day!
