.Don't know about Scarlet Law, but there's a chance that it's the same music.
Indie devs can't really afford to compose their own music, so they use royalty free stuff.
Big chance you hear some of the songs here somewhere else.
I mean, I heard the "sex music" in a local burger king ad.
And the "farm music" in a health insurance ad.
Either way, the prologue music when you get to the flat is Memories by Benjamin Tissot.
