How do I edit song metadata in Node using C++?

I 开发者_运维问答am trying to make a program in Node that automatically fills in metadata for a song (album,artist,name,etc.)

Is there a module out there that would let me do this? If not, how would I write one in C++?

If you're talking about ID3 tags, you can try Tim Smart's node-id3. If you have npm installed just:

npm install id3

It seems written in JS using async calls.
