We reported yesterday on the launch and swift removal of a tool called Downloadify on Google’s Chrome Web Store, which allowed people to automatically download MP3s of the songs they streamed through Spotify’s web player. This time yesterday morning, the tool could still be found on developer website GitHub, and it still worked. 24 hours later, Spotify’s engineers have managed to block it. “Seems like @Spotify fixed the player,” tweeted its developer Robin Aldenhoven. “The extension doesn’t work anymore. Still no official response…” We’d suggest he doesn’t hold his breath for that. Aldenhoven is likely to be just one of many developers poking at the seams of streaming music services to see if their DRM works, though. For Spotify (and Deezer, and Netflix/Hulu for that matter) tools like Downloadify are going to be a fact of life, just as they have been for YouTube down the years.
