What a song [Shinseiki no Love Song, first track]!
There are two "parts" of the song. By parts I mean that each has a different vibe.
It starts with a beat reminiscent of "Mustang" and of the "Fanclub" album. Gotoh sings in a style which is sort of like a rap. The instrumentals are interesting and experimental - but I like it. Kiyoshi has a nice groove going on the drums too. After about the 2:30 mark, things change. Like it has evolved from the previous style. It's just amazing and you'll definitely fall in love with Gotoh's singing. The song lasts just over 5 minutes.
