Subscription music services are my preferred way of consuming music. I had a Zune subscription for over two years (eventually cancelled when I lost my Zune and just started using my iPhone... Zune's big weakness was its hardware exclusivity), and I signed up for Spotify premium as soon as I could. I like sub models because I am paying for music, I can get whatever music I want (almost... bands like Arcade FIre don't license their music to these services I've found) whenever I want, and the actual data is well-manicured in terms of metadata.
