This site has credits. They'd be:
Kenji Ito: 01~04, 08, 11~13, 16~18, 21, 24, 25, 27, 29, 30, 34, 35
Atlus Sound Team (Kenichi Tsuchiya, Atsushi Kitajoh, Ryota Kozuka, Toshiki Konishi): 05~07, 09, 10, 14, 15, 19, 20, 22, 23, 26, 28, 31~33
Makes perfect sense and matches what Xenofan posted, and I think that site is usually accurate, but no source is given.
EDIT: Thanks to Api-Vat for the scans, confirm the above. Atlus team gets the shaft with no individual credits tho.
'Devil Survivor' was in caps in the spine, disc and (arguably) logo, so caps it is now.
