Funnily enough, Mastodon's parser doesn't seem to like https://🎵.ryandlewis.dev, but that's actually a valid url (try it in your browser bar!)
Granted it gets interpreted to https://xn--ml8h.ryandlewis.dev/, but the link is still valid!
And one of these is much nicer looking than the other.
Ah, it's because of the whole "replacing emojis with embedded images" thing...
