I'm not saying what I've voted for but am expecting Whole Lotta Love by Led Zep to be top, provided the 'kids' of today have actually heard of Jimmy Page et al!!
i voted for jet because i do love that guitar bit, but where is plug in baby muse or all my life Foo Fighters or loads of other great stuff. Stones Roses pah ;-)
If you or anyone's interested there's a Documentary tonight called 'The Joy of the Guitar Riff' BBC4 9.00pm. Contributions from the likes of: Dr Brian May, Dave Davis, Joan Jett, Nile Rodgers, Tony Iommi, Johnny Marr... the list goes on.
