... one might note that the mainstream industry has very little appeal to people that are intellectual or at least deeply interested in the actual content of their music.
The mainstream studios that are cracking out 'hit' after 'hit' (aka: highly advertised until people like it) are producing basic melodies in C Major with 'artists' that cannot honestly perform well on stage and likely can't do their music well in a true LIVE setting.
The mainstream studios are facing REAL ARTISTS and losing. What should they expect? They think they can churn out half-assed simpleton music and not be out-competed by bedroom producers with less than 5 years experience? Please... Mainstream music is awfully easy to make. 2 or 3 basic chords. Very little elaboration or demonstration of musical mastery. Major key. Generalized/Simplified/Non-confrontational/obvious/regurgitated lyrics. Chorus-Verse-Chorus-Verse-Chorus. Except you call the 'chorus' a "HOOK" now because it's usually very simple and has a catchy jingle.
Yeah. Lame.
Full disclosure: I've been a bedroom producer for 18 years now. I have a successful conscious hip hop crew and produce more complex and better music than most mainstream labels - check my sig. My emcees are more skilled than most of the latest studio-emcess, and they have great stage presence, and we have actual artistic/intelligent lyrics that have value beyond simple entertainment. I've been making music since before it was easy. MS-DOS was the OS when I started.
