Sure, the music is awesome, but Waters is a lyricist and a musician, so I guess there's no excuse for him not to come out with new notes or grooves. I knew that they were both concepts from The Wall period, and I'm not trashing the album at all, I enjoy pros and cons a lot just the way it is.
I was just wondering how many of you guys noticed this also, and what other similarities have you noticed.
Thanks!
