Does anyone know the song Akagi-senpai was singing?

i doubt it exists...and even if it did no one can know which song it is, even the one who was singing doesn't know (akagi)

Mh... I tried to get the lyrics through the drama CD (there is one apperantly) but I can't really find them, even with the english translation it won't work for me...

However, for those who want to listen to the Drama CD:
