Whether you like Napster To Go, the online store's new music subscription service, depends on whether you think of it as all-you-can-eat or all-you-can-pay.

Both descriptions are accurate. For $15 a month, Napster To Go offers unlimited song downloads — in a copy-restricted format that can be played only on Windows XP computers and some digital music players — but these songs expire if you don't keep paying that fee each month.

Here is BugMeNot.com for convenience. I would be interested to know how many "some digital music players" really is. Here is your answer:

Because this underlying software is so new, Napster To Go is the least compatible music store in existence. You can use it only on a Windows XP computer running Windows Media Player 10, and you can transfer your downloads only to a Windows Media-compatible player that includes special software and circuitry to enforce the pay-to-play deal.

Nine devices are compatible, seven needing software update to work with Napster To Go. Odd licensing limits the actual library available to To Go users. I see that I am not the only one (my original opinion on this subject) who didn't think this sounded good. It was good to read Rob Pegoraro's first hand account in this Washington Post article.

Consider this example: I have been purchasing CDs for about 20 years now, in which time I've accumulated about 300 of the things. At an average of $15 each, I've spent $4,500. Now suppose that, instead of buying those CDs, I could have opened up a Napster To Go account back in 1985. My total bill would be $3,600 and counting — and although I might have accumulated a larger, more diverse collection, I wouldn't own any of it.

That is a much better example then I came up with.
