About this extension
CrateCheck is a tool for DJs who discover music on Spotify and SoundCloud but buy it elsewhere. It puts a button next to every track. One click shows you where to buy it and whether you already own it.

HOW IT WORKS

• Open a playlist on Spotify or SoundCloud. CrateCheck adds a button to each track.
• Click the button. It checks the stores DJs actually buy from, like Bandcamp, Beatport and more.
• Results come in as each store answers, so you can go straight to the right page.

On Firefox, clicking a track's button updates the sidebar if it's open, and otherwise shows the results in a small floating window. To open the sidebar itself, use the toolbar icon or right-click a track and choose Find with CrateCheck.

KNOW WHAT YOU ALREADY OWN

• Connect CrateCheck Desktop, a small companion app for your Mac or Windows PC, and CrateCheck marks which tracks in your Rekordbox or Serato library you already own, so you can see what's still missing from your collection. Your library is read right there on your computer.

PRIVATE BY DESIGN

• No account, no sign up, no server of our own. When you click a track, its title and artist go straight from your browser to the music stores, as a search. CrateCheck sends us only anonymous usage counts, which never include the music you search or own, and, once you've agreed in the sidebar, crash reports when something breaks. An error message could rarely include a track name. You can turn both off any time. CrateCheck doesn't collect your location. Your DJ library never leaves your machine.

CrateCheck doesn't take payments or download files. It finds the track, shows what you already own, and points you to the store.
