YamaPi's speaking voice is very different from his singing voice. esp in "Home Party!!". even though i knew YamaPi was in it, i was like "WHUT. THAT DOESN'T SOUND LIKE PI".
but Hina/Yokoyama were painfully obvious if you've heard them speak before. haha.
i actually like Tackey's solo songs thus far...like all of them released in solo singles, at least. i prefer them to his solo songs found on T&T works. but maybe that's because Tsubasa's solos overpower his. LOL. Tackey's solo on the "Venus" single was so boring. :|
