@Kuroi I thought it'd be better to keep the pinyin, but in hindsight it absolutely helps with pronunciation and reading the words. The main reason they don't need tones is because when the lyrics are sung, they aren't using tones anyways. Imagine how weird Chinese music would sound if they had to use tones in every single lyric. It definitely wouldn't be as melodious as it is.

Official Chinese pinyin lyrics can go with or without the tones. I've noticed that with a lot of albums like Jay Chou's or other CPOP stars. Also, in terms of VOCALOIDs, blogs like saberbutterfly's tend to have pinyin lyrics without tones.

It's more organized, easier to read and because the chinese characters are right there next to the pinyin, all you have to do is look over for a reference if you're really confused as to what word you're saying.

In conclusion, it's not necessary and I think it's fine to rework all the pages to  go without pinyin. But that's just my two cents.
