I’ve discovered Pandora – the web radio that creates a custom playlist based on music you like. I’m using it to play “spa” music on my laptop while I work. I find it helps me concentrate and keeps me from distractions.
I had started to get new stuff for my iPod (there’s only so many times I can listen to the Hawaiian thunderstorm even if it does keep the cat away!) but the variety of stuff on Pandora is great, it doesn’t repeat, and it’s FREE.
