All I can say is don't buy into it. Don't support the rip-off mechants that are the record companies. They charge enough already for CD singles but this is worse value, compared to the quality you get on a CD single. There you get a physical product that you can play on whatever you choose, in a format you choose.
£1.10 for a compressed DRM-protected WMA file is very poor value if you buy the track outright.
I don't have a problem with the DRM there to control the subscription based model where you buy an monthly sub where you can listen to as many as you want, but if people go and buy it outright, then you should be entitled to have the DRM free uncompressed wave file IMO and also covers if you want so you can make your own CD.
If this service does take off, then it maybe the end of proper CD quality music as we know it
