This is a true endurance test on drums. Sure, it's kinda slow and simple for the first six or seven minutes - enough to turn some people off since that's longer than most songs in the game - but that's just the lull that lowers your guard for the rest of the song.
As mentioned, the opening bit with the vocals and introduction to the song - about 6-7 minutes or so - is kind of boring. It's simple, probably a 1/5 or 2/5 difficulty at most. Slow, easy to hit the notes, and a little on the repetitive side.
But once the guitar and bass slow down and have their breaks, the drum solo picks up, and the song is utter gold from there on out.
It all starts with what is quite possibly the longest drum solo in the entire game, 78 bars or something like that, with a steady rhythm of the bass drum overlaid with a bunch of sweet drum rolls and fills for I think two and a half minutes of bliss.
After that it slows a bit but the rhythm is still fun and alternates from one stick to the next, then it picks back up in an extended outtro similar to the solo but a bit faster and requires utter perfection.
this song is HARD, and worthy of its max tiered position, even if it has an extended simple part. The solo is great, and in total there's about 9-10 minutes of utter bliss aside from the slow opening. Lots of fun, but be prepared for an endurance test.
5/5 - Great but be warned of how exhausting it is.
