Yeah but subscription DRM is a cool idea. I've only bought test songs from iTunes and would never pay for that. Napster, Rhapsody offer barely better in terms of quality and are even more restrictive in terms of how you can use the music if you're foolish enough to buy from them, but the alternative they offer is that you give them a certain amount a month and you can download the entire catalog onto your player. i.e. you rent music instead of buying it. Of course when you stop paying you lose all access to the music but I use it like a try-before-you-buy CD catalog. It's great. It's already saved me hundred of dollars in dud CD's that I would have bought if I wasn't able to check it out in full.
When Apple offers it, I'm out of the truly crappy renting experience that is Microsoft PlaysForSure Subscription and will ditch all my non-iPods with a sigh of relief. Nothing ever really works properly most of the time (and despite what I said about iTunes, I will acknowledge that it works perfectly) and sometimes it's such a hassle to get music onto a player that I do sometimes question whether this is really worth it. It is for me, but PlaysForSure and the players which use it are just a series of unnecessary hassles that I wouldn't have to put up with if it was Apple stuff.
