Lol.I suppose the riff question is tricky to answer off the top of your head.I dont know all the guitar terms but in Foxy Lady by Jimmy Hendrix,before he sings the line Foxy lady he plays a nice bit of guitar I think.Hendrix is another guitarist I like.
Also in Under the bridge by RHCP there is nice guitaring I think.This song lyrically is one of my favourites too.
Welcome to the Jungle by Guns n Roses has guitaring in it I like.
Hi.I like guitar focussed groups with strong lyrics. Foofighters, Alterbridge ,Metalica,Smashing pumpkins,Muse,Linkin Park,POD and othersI like some rnb and classical also.I try to listen to music most days.
