ololol is dis sum Carimna Burana? Though you're probably using it as a reference to One-Winged Angel, which stole its lyrics from it. (edit: wait never mind I forgot the "O Fortuna" stanza isn't in One-Winged Angel, so it has to be the Carmina Burana; you're probably referring to Carl Orff's famous adaptation, although there are several others).

I don't really care enough to put up lyrics, so someone else do some
