I think the song (Zous) sounds pretty good overall, although there are some inconsistencies in the guitar riffs, like they were taken from several different sessions (which I assume they were) and then slammed together, quick and dirty. But Zous is obviously the product of a lot more than an hour of your life's experience. You draw from production techniques and melodies/themes that have probably been running through your head being refined for years, and used in other songs you've previously done. It's "you".
And even if a song is "easy" (for one particular person) to make, does that make it bad? What if that person is really talented, or has a style that is interesting to others?
PS - I thought I recognized something from 3:12 to 3:20, a riff from Rigor Mortis - Sunset that I remember from 2001 when I had been in the old mp3.com community.
