I just wanted to bring up a discussion on cut-and-paste songwriting akin to Mr. Bungle, Candiria, Between the Buried and Me, Dream Theater, Meshuggah, Opeth, etc. Although there is little to no correlation between riffs, phrases, movements, or seemingly anything as far as natural/tonic/theoretical/well-written transition between segments of these bands' songs, is it all really such a bad thing? Mr. Bungle and BTBAM definitely write that way on purpose, and I certainly appreciate the random wackyness that comes with unexpected style, riff, time signature, volume, vocal, instrument, or speed changes that seem illogical but grow endearing and expected through repeat listenings. Is this bad songwriting or simply a different approach? Do songs always have to have a set pattern and logical passings of musical development? Can't cut-and-paste work?
