Song of the Day

One song a day. The one that hit hardest.

Paste a song link (Spotify, Apple Music, YouTube, SoundCloud, Tidal, Deezer), add a caption of up to 100 characters, and it lands on the Globe of everyone who follows you. At your midnight it moves into your archive, where each month becomes a playlist.

• The Globe (/): a slowly spinning sphere with a tile for each person you follow, showing their album cover or a "not yet" tile. Drag to spin, pinch or scroll to zoom, tap a song to bring it up close and flip it for the caption. The glowing core at the center is your profile: tap it or zoom in to fly in.
• Your core (/u/<username>): streak, songs shared, usual post time, today's song, monthly playlists and the full archive.
• Demo (/demo): the Globe with made-up friends, no sign-in needed.

How it's built

• Next.js 16 (App Router), hosted on Vercel
• Supabase for sign-in (email link) and the Postgres database
• song.link / Odesli to match a song across platforms and find its artwork
• Playback is always the platform's own embedded player. Nothing is hosted here.
