As a fan of online music downloads since the days of swapping mp3s over IRC channels, I knew this was inevitable, but I finally...signed up for iTunes. It's a great service that provides quality music at low prices over the internet. They also have failsafes to ensure that an iffy connection and a failed download won't rip you off (all purchases and downloads are tracked through the service, and anything you didn't finish downloading can be downloaded later). You can also subscribe to regularly downloaded podcasts and they even offer TV shows for sale. I finally see why it's so successful, and I would recommend this service to anyone.
