Alright Fellows, that was harder then I thought! Frankly, I don't like to rank anything, especially music.
But... after a lot of thoughts and hesitations I finally managed in doing it. It still doesn't mean that I won't change
my mind in the future, but here are my top 10, arranged alphabetically & combined with a bit of nostalgia:
Alice In Chains The Beatles Chris Cornell (& Soundgarden) Days of the New Dream Theater
Alice In Chains The Beatles Chris Cornell Days of the New Dream Theater
Extreme Guns N' Roses Pink Floyd Porcupine Tree Queen
Extreme Guns N' Roses Pink Floyd Porcupine Tree Queen 

Once again, these choises were not an easy thing to make, but I stand behind them (sort of...).
