Your playback quality is still (I consider, severely) restricted[1], among other features I might not be aware of. They might also start injecting ads into the audio stream soon, if they realise ad blocking methods are popular (Twitch has done this for example).
While that is a very funny sentence, the half a cent I'm withholding from the artist by blocking the ad is hardly a robbery.
Just buy a CD once in a while if the guilt is too much to handle.
