There was only one part of Tears that I really think Toshi shouldn't have done, which was the way he sang the end of "kodoku wo dakishimete", apart from that it was fine, except for a couple of iddy bitty parts where Toshi did a couple of rasp sounds in the verses where I guess he shouldn't, I still think it was one of the most emotional and Toshi's best live performance of the song though.
However he's got to now realise a bit more where not to include his screaming in a song, and I really can't tell if he was trying to avoid the high notes or not, I mean look at that forever love video from the 26th, he was perfect there, and during this countdown performance there were moments in like X & Rusty Nail when Toshi was singing the high notes, so I don't know wether he was trying to avoid them or just trying to sound different, but he should not sing "kodoku wo dakishimete" and other emotional lines in a ballad song like that ever again, I think it worked with the rest of the song, but just not that specific part.
