ain't it fun and sympathy for the devil should be nowhere near a gnr greatest hits album
fucking indeed
I think aint it fun was the best off TSI?, (along with New Rose...) and sommething rightfully had to be included from that album, so IMO that as the best choice
As for Sympathy For The Devil, as it was a single only release, i think it was a good move to include it as otherwise a lot of fans would be unable to hear it, and as its a faily good song, and imoortant too as it was the final release from the orginal band, so it was good to include too.
Just my 2 cents...
