My suggestion is to have a 'Discussion' section in the 'Album' section so that posts like....for e.g.... 'favorite Tool songs', 'least favorite Tool songs', 'If you could only have 1 song from each album.....', 'Schism and Intolerance are parallel songs' and so forth would go in there nicely.
It would stop the cluttering in the normal Discussion section. I know there is the 'concert art' but that doesn't work with these kind of topics. Anyway it's just a suggestion.
