I'm assuming you want any feedback. I'm not trying to hate on your music, just going to be honest. Also I'm not an expert in any way, but I've been a fan of rap since I can remember. That being said I've been known to be overly critical so take what I say with a grain a salt.
Fly Type of Day
I like the beat. I didn't like the vocals and the chorus though, they didn't seem to go with the beat. Actually the chorus I'm not liking at all really.
Modern Day Rebel
I like it, no issues with it at all. Sounds like something people get paid for.
This is love
Didn't like it. Again something seemed off. The beat seemed kinda droning and the chorus seemed long.
Untitled
I like it. Again seems like a professional studio song. Kinda sounds like some tupac songs. Well written and emotional. The beat almost sounds like an NES game or something else retro, that's a bonus.
This is my favorite on the list. It needs a name.
Furious Styles
Didn't really like it. It's not bad just not the style I like. Reminds me of Bone Thugs N Harmony. That's not a bad thing at all, just not my thing. For what it is it sounds good. Nothing seems out of place or anything.
Miles Davis
I like the beat, sounds old school for sure. Kinda reminds me of Nate Dog and Warren G, that's not a bad thing either. I wasn't liking the chorus here though. Seemed to go on too long.
The City
First off I really like the guitar. Everthing else sounds good. I think the guitar makes it though, it's simple but it carries the song. One of the better ones on the list.
I listened to each song twice, the player froze on the city the first time. Hopefully you don't mind me being totally honest. Like I said I'm not claiming to be an authority on music.
Also which parts are you doing? I'm not familiar with what you guys do.
