I agree with you but there is a difference
It's a marketing ploy. Now if an artist is on a major lable with a big budget a street album would be something that they independently released. IE TI dropped that mixtape that f*cked up LIL FLIP'S career. If an artist is already on an independent label a street album would be a cd put together in short time spand (ex 2 weeks) cause some cat gave them upfront $$$ to do an album with them. A perfect example is any album released on JOHN SILVA'S label HIGH POWERED ENTERTAINMENT. If you don't know by now every album released on this label should be considered a "street" album cause they all sound generic with maybe two or three good tracks on them. DAZ, KILLA TAY, KURUPT & ROSCOE have all released albums on this label and as good as those 4 artists are all the albums are weak because the beats ain't sh*t!!! I hope this helps.
