I don't get it. Why do so many Mac users assume that whatever Apple does must be gospel??? I don't *want* to own a movie!! I have not purchased a movie in my life. Ever. There are only a very few select movies that I've seen more than once (e.g. Star Wars trilogy)
Same goes for music. What's so great about owning music? I could see if you were really into owning the *physical* product, with the cover art, liner notes, etc. But if we're just talking a pure digital product, what value is there in owning it? The utility I get from music is from *listening* to it, not owning it!!! Since music subscription services let me download, on demand, just about any song I can think of, they provide me with *vast* utility for a measly $15/month or whatever the service costs. It's about the best $15/month you could spend on *anything*, IMHO
The only objection I could see to music subscriptions is that once you've downloaded a bunch of music, if you cancel your subscription you "lose" the music. But believe me, that's *not* a big deal. Having taken Rhapsody, Yahoo! Music, and Napster for test runs, I can tell you that it's not that big an inconvenience. The major subscription services offer pretty much the same catalog of music, so the next time you feel like listening to a particular song/album you just search for it and download the album. The music can play while it's downloading so it's almost like you already had it on your machine anyway.
In summary, I think people that some people tend to criticize music subscription services even though they have no experience with them. Try them if you have a PC handy (or Windows on Bootcamp/Parallels). Once you've tried a subscription service it's definitely hard to give up. I'm hoping Rhapsody, Napster, or Yahoo Music! eventually comes out with a Mac client of their software...
