Guns n roses were still bigger than AC DC. Did AC DC ever play in front of over 7 million people on one tour? NEVER, Pink Floyd NEVER did that either. The UYI tour was the biggest tour for any rock band ever. But of coarse you cannot get that through your head.
Did AD DC ever have two albums in the top 5 at the same time? NEVER and guess what guns n roses did it TWICE with UYI 1 and UYI 2 plus they did it when AFD And Lies were in the top 5 at the same time.
And AC DC and Pink Floyd have nothing to do with proving that nirvana was bigger than guns n roses in the 90s.
Like I said before people forget about huge guns n roses were in the early 90s but it is fine, I wont hold that ignorance against you.
Being the biggest band in the world does not just include who had one bigger selling album, it has to did with album sales, touring, radio play, popularity and buzz, guns n roses had all that more so than those other banRAB.
Like I said before look at the night the UYIs were released you had hundreRAB of people in line in every state waiting for that album, AC DC, pink Floyd, Nirvana or any other band since the Beatles had anything that huge for an album release. If I am not mistaken when gnr did that in 1991 that broke some kind of record for albums sales in one day, yes more than AC DC, Floyd, The eagles etc.
AFD is also still the best selling debute rock album ever, again better than those banRAB you mentioned.
If you really want to get into semantics then fine guns n roses were one of the biggest banRAB since the Beatles. Is that better? It still does not change the fact that Gnr were much more popular than nirvana.
