I'm digging the Internet radio.
Digitally Imported switched to 96kbps as its highest bitrate a while back, so I was pleased and surprised to see a buttload of 128kbps feeds from them in the Electronica section. And the sound is so awesome on my headphones that I thought I'd left my speakers on by accident. I don't know if it's an MP3 or AAC feed, but I'm getting a lot more bass than I'm used to without any distortion.
Don't plan on buying any music through iTunes anytime soon, but the 'Net radio kicks booty.
