why did guns 'n roses no longer exist?  

I dont know why but I used to listen to them when I was teen.

Guns and roses split up because the lead singer got power mad and the rest of the band wouldnt tolerate it. Although, they do still exist but it is only Axel Rose and a whole different line-up. they have actually released a new album not too long ago called Chinese Democracy. Also Slash, Duff and the drummer went off to do Velvet Revolver, who are a awesome band =]

G N'R still exist with a totally different line-up bar Axl. They have recently released a new Album (Chinese Democracy), but of course, as mentioned above, Axl (Lead Singer) got power hungry and, the original members wouldnt take it, so thats why you dont hear a lot, as Chinese Democracy hasnt done as well as people thought, bt lets see how things pan out.

Guns N Roses in no longer exist anymore the one who exist is just Axl Rose and a band who played all old GNR songs. i think why Axl still use GNR name, why he didn`t change the band name. GNR are : AXL, Slash, Izzy, Duff, Steve. and no one gonna break this line up. in my opinion GNR today is just Axl Rose`s Band.
