I completely understand. Just one minor feature though, and it's entirely optional. The real meat is in the "subscriptions", which rely on more steadfast services like Last.fm and Spotify.
Awesome! I hope you like it. I've successfully converted my household from Spotify to Plexamp using this. Setup a few subscriptions, let the new artists and recommendations roll in, and you have a constant stream of new music.
The Discover feature is pretty much identical to what Lidify does. The distinguishing feature is the Subscriptions though. Like automated Lidify.
