Shuraba for me.
Overall, anything by TJ has become a hit or miss with me (by miss I mean good but still likely to skip). The only single that has escaped that is Shuraba. Gunjo is just a weak single, first two songs on it are okay and Kao is really good. Sounan is good as is Kokoro but Dynamite freaks me out a little. Shuraba is averagely good I can't openly bad mouth any of the songs (Koi wa Maboroshi gets close thought with its double entendre). In OSCA I tend to skip Pinocchio cuz it gets boring half wa through.
