Composed by Fukuyama Masaharu (the actor who plays Yukawa in the drama) and Kanno Yugo, many pieces are performed by Fukuyama on guitar, and female vocals are by the lead actress Shibasaki Kou. Listening to the soundtrack always brings back memories from the drama, particularly the driving guitar version of "vs. ~Chikaku to Kairaku no Neji~" (always played during the critical scene when Yukawa goes into his frenzied equation writing mode on the nearest flat surface) and the ending theme of the first season (not named here because the spelling in romaji includes a word too similar to a disallowed English word). It's an extra treat to know that the two acting leads of one of my favorite dramas are also such talented musicians.
