I downloaded iTunes today and it has to be the easiest way I've found of downloading and playing music to date.
I've tried all the others like the Coke site, OD2 and the various music company sites and this seems the best so far. I can live with79p a track as it will allow you to download a particular track from an album. Seems to be a good choice of artists and also some exclusive stuff. I can see why it was so successful in the USA.
