I think you also need to call (emms-track-updated track) afterwards to
have emms pick up the change and update track info in the playlist
buffer and such.

Don't think anything else is missing or incorrect, but if it still
won't work, maybe check how emms-player-mpv-info-meta-update-track does
it, as I implemented similar async info update on mpv event there and
it seem to be working.
