What can I say, it was one of the debut albums in history, very professional made. As I think about, Guns N' Roses have been all the time pros in they way they handled their production and shows. Their life, personal and as band is/was a mess, but everything they delivered was top notch.
For their debut album, they made more songs than needed. They've chosen the ones that they liked the most and the ones who would best fit from a lot of point of views. They wanted to have only a ballad on it, so November Rain was left out. Yes, that huge hit did not make on the debut album. Another song was chosen instead:
For me, Guns N' Roses was one of the first rock bands I start listening. I was 10 when I discovered them, with Don't Cry which was aired on MTV, when MTV was playing music.
My wife and I managed to see them 3 years ago, when they have been in Munich. They were not anymore young. Life changed them, but the music was still great.
So, happy anniversary!
