Yes, I think that this problem is all too common with beginning producers (and even some very experienced ones) who spend way too much time trying make their mix sound "pro", when the 7-minute song itself has nothing musically interesting in it to keep my attention for more than 20 seconds. Songs that go nowhere, have no melody, and, hell, often not even a chord change, but, the mix actually sounds pretty good - I find this to be the case more often than not on production forums. IMO, the primary purpose of the production part of music-making is to bring out the musical ideas, but too many people think that they can get away with skipping the hard part of creating great musical ideas simply by having a stellar production. IOW, yes, you certainly can polish a musical turd, but it just leaves you with a shinier (overproduced) turd.
