I posted this earlier, but it got hung up in "moderation".
1. Dream Theater
2. Foo Fighters
4. Sum 41
After listening to all the songs and learning about the process I believe DT has a real shot at winning. I don't think FF will get it because Dave Grohl screams the song. Mastadon picked silly lyrics and a dull pace. Sum 41 has moments of promise, but the song just doesn't come together. Megadeaths song is repetitive and sounds like most every other Megadeath song. The songs are pretty good and catchy, but they don't compare to .....
DT's song is just plain better musicianship, sound and melody. I don't believe the song length will be an issue because of how the song evolves and balances. Plus the lyrics are timely and put a language to something everyone can relate to.
