I don`t understand what Nirvana is doning in everyone`s top 10 and I don`t see Dream Theater anywhere...Nirvana is highly overrated (come on everyone, Smells Like Teen Spirit is just an average song), and DT underrated. My top 10 would be:

1. One - Metallica (What an awesome solo )
2. Home - Dream Theater (The sphere is great)
3. A Change of Seasons - Dream Theater (DT`s epic )
4. Master of Puppets - Metallica (cool riff)
5. Queen - Bohemedian Rapsody (what can I say?)
6. Stream of Consciousness - Dream Theater (great melody)
7. Child in Time - Deep Purple (classic)
8. Fade to Black - Metallica (a lot better than NeM)
9. Stairway to heaven - Led Zeppelin (beautiful)
10. Sanitarium - Metallica (and yet another ballad )

Now this is a great list without Nirvana and with Dream Theater
