How It Works
Share any music link (Spotify, YouTube, Bandcamp, whatever) in our Slack channels
Our system automatically finds those links and translates them into every platform the track is available on
Background jobs also grab genre tags and release dates from Spotify’s API
Everything shows up in a unified view where you can filter by genre, sort by release date, or browse by channel
Find that sludge metal track someone shared last month without scrolling through 1,000 Slack messages
Notes from Building
Communities create the real requirements, not the roadmap.
Once we saw how people were actually sharing music, the problem became clear. The Slack community created its own digital desire paths. People shared links from every platform, in every format, across every channel. The goal was never to force everyone into one clean system. The goal was to support what they were already doing.
Let specialized tools do the heavy lifting.
Songlink, aka Odesli, takes any music link and returns the same track across a long list of platforms. It solved the hardest problem right away. We send every new link through it and get back the full set of platform matches automatically.
Crosstracks connects the messy parts.
Slack gives us the messages. Songlink/Odesli gives us the cross-platform matches. Spotify gives us genres and release dates. Inngest runs the background jobs that tie it all together. One job syncs messages from Slack. One processes links through Songlink. One fetches metadata from Spotify. All of it runs quietly in the background.
Build for what people are doing, not what you assumed they would do.
Just like we did not try to rebuild Slack, we also did not try to build our own metadata service. We watched how the community behaved and picked the tools that supported that behavior. The magic is in connecting the pieces. The result is a unified place to browse every recommendation, with full platform coverage, genre filtering, and release date sorting, all shaped by real usage.
