When putting albums in the game, quality is not a factor at all. If an album only has a few songs, in order to keep things moving smoothly, you need to put in another one.Yes the more albums you throw in at the same time, the more strong concurrents you throw in the game. It depends on the quality but these two are mighty albums.
Remember A Day
Shine On 2
Pigs On The Wing (both parts)
Animals is the best Floyd album. The concept, the three epics, Gilmour's playing! It's all so good. I'd put all 3 of the big songs in the top ten. With Sheep having one of the greatest outros ever written.
