Wouldn't it be useful to be able to translate artist/band names?
I personally see no utility in that as proper names can't be translated (they can be transliterated). How would that work?
How would it be helpful for those who don't speak the language? It's not going to make finding the artist any easier. Online shops or labels never do this, they sell and release albums as is with the name of the artist/band.
However we do encourage users to submit the romanized (transliteration) of the name of an artist/band like: 孫露 (Sun Lu) ジン (Jinn), Ария (Aria), etc.
I find it relevant to know the meaning of the names. To know how they correspond to their songs.
It isn't necessary though, we have plenty of lyrics not translated at all.
