The Irregular at Magic High School episode 17 French rap credits I am trying to find the name / info on the French rap song played at 21:30 of "The Irregular at Magic High School" episode 17.

Does anyone know anything about it?
Is there a database that holds the music credits of anime?

I have googled everywhere and even shazam'd the song on my iPhone but did not find anything .

Any insight will be great
The name of this song is Metaphore 2.

It's found on the The Irregular at Magic High School Original Soundtrack 2 as song #20.
