This may seem trivial or an extreme use case, but many artists have a.k.a’s or alternate names. Cat Stevens as Yusuf Islam, Danger Mouse as Brian Burton, etc. It would be great to have a link from one name to the other. For instance, when browsing Cat Stevens, you should be able to click on a link and go to Yusuf Islam. That’d be great.
It’s up to the meta data providers to embed the link. Some artists do have them, in fact there was a thread complaining about it.
