I have Spotify but rarely use it.
I use mine everyday for the Go Birds! daily podcast but that would be free without a sub.
I find I use the music enough thats it's worth $15/month to me.
I am rather old school and still have my own MP3/M4A collection of music
Live long enough and MP3's will make a comeback with whatever younger generation like records.
I do kinda miss that 80gb iPod I had with the wheel that could play music and video. That was the only Macintosh product I've ever owned.
