usually start rapping after 4 bars

I record about 4 songs for my first mixtape in like years ..and i most say they sound good but i feel like it not on the level it needs to be ...also i only half like the song meaning i really only like 2 of the 4 .. but hey there still time .. and im still written ... so im a jus keep kicking it and i cant find all the beats i want .. starting to piss me off but hey .. it will all come around !
