Zane - Most Konami games gave individual sound credits in the end credits at least. At SEMO, I've tried to provide accurate game credits for their popular series / composers found here:

The section is due to be expanded and, for some games, more composers might be involved than listed. It's definitely the best available right now. GMCL is very good for individual composer credits for Konami titles, though in Japanese.
Anyway, some of my favourite lesser-known composers:
Kenichiro Fukui - I respect his versatility and meticulousness on projects like Einhander, Front Mission 5, The Black Mages, Violent Storm, Hanjuku Hero 4, and Project Sylpheed
Keiki Kobayashi - While the Namco Sound Team gets quite a lot of recognition, I feel the individual composers lack it and I've found Kobayashi's Ace Combat works to be the best of the lot
Kenta Nagata - I thought he did a great job establishing the nautical sound and making the main themes for The Legend of Zelda: The Wind Waker while Mario Kart 64, Big Brain Academy, and Animal Crossing demonstrated his broader capacity
Mutsuhiko Izumi - I hear a lot about amazing game music guitarists, but Izumi is definitely underexposed. Although I don't follow bemani much, his earlier Konami contributions are also impressive, especially the TMNT and Snatcher series
Masami Ueda - I've heard a lot of credit for the Okami soundtracks, but Ueda's work on Biohazard 2, Devil May Cry, and the Viewtiful Joe series was fantastic too.
Masato Kouda - Former Capcom composer who has gone strength to strength on the Wild Arms series while also making formidable Devil May Cry, Darkstalkers, Monster Hunter, and Star Onions contributions.
Yoshino Aoki - Continuing with the Capcom theme, I love Aoki's works on Breath of Fire IV (and, to a lesser extent, III) and Mega Man series.
Hisayoshi Ogura - As far as historical figures go, Hisayoshi Ogura is right up there with the best. I respect how he's led the Zuntata team and also enjoy his Darius, Zoids Infinity, Arkanoid, and live works.
Toshikazu Tanaka - His SNK soundtracks manage to be so creative without loss of accessibility or energy. Metal Slug 4 & 5, Gaia Crusaders, and King of Fighters Maximum Impact 1 & 2 are all excellent.
Kohei Tanaka - Pretty well known for his anime works, but I wish the Alundra, Tengai Makyou, Sakura Taisen, and Lennus series would gain more recognition.
Takayuki Nakamura - I have a lot of respect for this guy. Interesting Sega past and he is now definitely one of the ones leading the industry in terms of fighting game soundtracks (Kengo, Guilty Gear Petit 1 & 2, King of Fighters EX, WWR Raw 1 & 2, Custom Robo: Battle Revolution, Ninety-Nine Nights, Ehrgeiz, Tobal 2). But it's his Lumines and Meteos work that I really love.
