Do you listen to shuffled mixes of songs on your iPod? It's pretty much all I listen to on mine. I have a series of smart playlists that are set up to give me a mix of stuff I love, along with new stuff and random other songs. It's like having my own radio station with a great mix of favourites and new stuff.
Although sometimes the mixes are a little shocking.
Take the example below. I was flying back from vacation, just snoozing and listening to a mix of high-rated tunes. I was grooving along to Tool's "Prison Sex" and as soon as it ended, I was greeted by a sweet, soft voice of Morcheeba's "Rome Wasn't Built in a Day". Check it -
