The vocals, imo, just aren't as strong in PTB as in TC.
Also, TC is just so catchy, makes me want to sing along..
PTB.. is ever so slightly boring. -shrug-
I do agree about the riffs, though.
That'd be bitchin.. but as it stands.. it's just too short notice for me.
If it weren't for my mum being all.. "Let's try and go to NY!" I would have just not even bothered with the idea of possibly going.
