100% agreed @evanw – but Spotify has actively shut us down. They’ve pretty much shut down everyone post-Spotify Connect (except Sonos, which they can’t afford to lose).
We do have working integrations with Deezer and Rhapsody, but because they didn’t give us their backend databases, the integrations feel like a bolt on, because we can’t match up the content on their network to content on your hard drives.
