Lantis has a Facebook page that posts album info bilingually, so that looks like a potential reference for name readings for folks on their recent releases:

Tomotaka Taira in particular.
Buuuuuuut, as Illidan noticed, it sure looks like they're copying notes from our entries and using them as a base: compare
them and
us (the kanji in their English section is the big giveaway). So maybe they're not a perfect resource, haha.
