For one thing, the interface is terrible.

Also, it doesn't allow me to access cloud copies of music, only my own library. Honestly, the concept of an "own library" is obsolete. I want a service that lets me stream anything I want (like grooveshark), with a powerful and intuitive interface (like old iTunes), and a "local library" feature (like Spotify) of anything I want for offline listening. Add in a worthwhile adaptive radio feature (like Pandora) with sharing capabilities (like last.fm) and you've got the whole package.
