Most of Tool is boring.
*flees*
They're my favourite band ever, but I can completely see where you're coming from.
Their songs could easily be called 'samey,' but they all have a really distinct atmosphere and feel to them for me. Like, Right In Two has a climax that's almost identical to Forty Six & 2's climax, but those songs feel really different throughout to me, even during said climaxes.
Also, Green Day. 5 years for 21st Century Breakdown? What the hell, it wasn't worth that wait.
