Adding on to this guy's comment, an instant copy url link button is ideal.

An "Open in browser" button within the 3 dots menu is okay to have, but a "copy link to (servicename)" button next within the bottom of the GUI is even better.

Copy link buttons are more ideal for a user to quickly share an artist, album, or song to a friend's preferred service to listen on.
(one click instantly copies the user's site service's link and sends it to clipboard)

This, plus an option within settings of preferred service to copy a sharable link from would be ideal for sharing. Another cool idea is to allow the user to simply select multiple services.

For example: artist, album, and song media pulled from VK, could still aggregate a youtube or spotify link to the song, rather than only linking to VK.

I drew a visual representation of what that looks like in the photo.
