I don’t know if anyone other than me will ever use it, but if you have feedback or spot errors, drop me a line here. (I am still studying Japanese so it’s entirely possible I’ve made some mistakes.)
Yup, Lyrical-Nonsense usually has them. Also I can often find lyrics from Google by typing in the song title (in Japanese, if the title isn’t in English) and adding “lyrics” at the end. You just have to check the quality to make sure they’re reliable, and ignore all the sites that only post romaji transcriptions.
FYI, I added a first lesson to the course to explain what my process is for studying Japanese songs, because memorizing vocabulary items is only part of it.
