Izzy # 17 on Rolling Stone's Most Underrated Guitarists

[Thorned Rose]

It blows my damn mind how Mick Mars isn't on that list...

amazing... that guy can play

[GeorgeSteele]

As long as I've loved GNR, I admit I'm still not sure which signature guitar parts are Izzy's.  I'm know the Don't Cry intro and DTJ riff are his.  What else?

[AdZ]

The first solo in Nightrain for one..

the electric solo in DTJ is Izzy to... it is credited to him anyway

It's a mistake in the credits.. it's not him. There are several credit mistakes, for example he doesn't play on Coma either.

Izzy's guitar is in the left speaker, he plays only leads on the intro of Back Off Bitch and the outro on RNDTH, intro on Estranged same as Slash, for the rest it's all rhythm.

But on AFD, he wote a lot of the main riffs.  Think About You, Out Ta Get me and Mr Brownstone are all izzy numbers.  He had the main intro for Nightrain, he wrote most of the music for My Michelle.  Aside from intro and solos, he wrote most of Sweet Child Of Mine.   Anything goes is mainly his. 
Also, i think Move To The City and Reckless Life are mostly written by him, Patience was mostly him (aside from the outro, which was entire band).  Used To Love Her is definetely an izzy number. 

So in the early days, he was prolific, but I think his contributions dropped out somewhat around the UYI era.  You Ain't The First, 14 Years and Dust N' Bones, and Perfect Crime are mainly his.

His contributions on UYI:

Right Next Door To Hell = music except the chorus which is from Timo Kaltia (lyrics are Axl)
Dust N' Bones = music/lyrics mainly Izzy
Don't Cry = music
Perfect Crime = had the idea for the music first but co-wrote it with Slash
You Ain't The First = everything
Bad Obsession = music and lyrics mainly, with West Arkeen also contributing
Double Talkin' Jive = everything
Bad Apples = some parts of the music
14 Years = most of the music and lyrics
Pretty Tied Up = everything
You Could Be Mine = most of the music and possibly some of the lyrics

[Rocket Killer]

....and that is correct

[Bodhi]

its nice to see Izzy made this list...considering Slash did not make Rolling Stones top 100 list a few years back
