For this to work you need a "Plays For Sure: Subscription" compatable device there are 4/5 of these around today and doubtless more in development.
The problem with the subscription model is that you don't just work out the cost over 1 year but over your lifetime, working on assumption that you will listen to music for as long as your ears work (and for youngsters that may be a full lifetime with advances in medicine). So what does this practically mean.
It means this is a simplistic view...
http://www.napster.com/using_napster/ipod_and_napster.html-for older listeners, like myself in my 30s, I have 400 albums so I am most of the way to filling my iPod anyway. So I get less benefit as I own much of what I like. I benefit from the browsing/discovering features, however paying 1p a track on MSN Music or buying the tracks from iTunes will make more financial sense. I can usually buy the full CD album for about the same (sometimes cheaper) price and the quality is superb.
In the UK it's £15 a month for Napster to Go. If I live 40 more years thats, 15x40x12=£7,200. Maybe not the worst value for money but hmmm not a bargain (especially as I own much of what I will like!)
- for younger listeners, say 65 years of listening for an 18 year old (you guys will live longer than me!). 65x12x40=£11,700. Not the best of deals. Especially as you don't get CDDA quality.
- the average consumer spends less than $90 a year on music, I think in the UK the figure is £60 (but this is from memory so I could be wrong but will be no more than £90). 90x40=3600 compared to £/$7200 OR 90x65=£/$5850 compared with £11,700. So in short the average consumer will have doubled his music spend if he signs up. Good news for Music Moguls.
Also this ignores the CDs that they have already paid for at least once before (oh and on tape, vinyl, 8 track, real to real, etc.)
You can see that if you have a small collection today but have just discovered music and will buy a lot in the future then it will work well for you. Get used to WMA though. Now if Apple offered this for the iPod in AAC I might be more enthusiastic :-D
