Artist Tag Separation Character
New to the site, so I don't know if this information is sitting around anywhere. Are there any characters we can add into the metadata of a song to indicate that multiple artists are separate? I have some songs where I have the artists separated by commas (Artist1, Artist 2) but they are treated as one long artist string instead of as two separate artists. I've heard that the semicolon ; is commonly used for programs like this, but it's not universal. Thanks!
(I'm referring mainly to the "Contributing Artists" field, but knowing this info for the "Album Artist" field would be great too!)
