Never really understood the whole "classic album" or "mixtape vs. album" thing either.
All a mixtape or an album is, is a collection of songs. Why does it really matter which medium it was presented to the listener?
When you're listening to a song, does the actual song sound any better if it's a loose track, a mixtape track, or an album cut?
shyt, a lot of Budden's best work isn't even on any projects. OLS 1-2, So Long Goodbye, Where Did It Go Wrong, 4 Walls, Outcast, Broken Wings Freestyle, Hello Expectations, etc.
Don't really see how that diminishes their value. Do they just not exist because they're not on a project?
