Near the top of the lyrics, you should hopefully see “Show All 1 2 3 4″

Show All => Show all lyric versions
1 => Kanji
2 => Hiragana
3 => Romaji
4 => Karaoke (Kanji and Romaji)

Hope this helps :) We’re now working on an easier way to browse lyrics and will gradually convert the ‘old’ system over to the new one.
