With the latest update to Python, radioactive officially just doesn't work anymore (unless you're on an immutable system, of course). Previously, moving files around worked fine, but now it probably just isn't worth the trouble of figuring out what to put where, so I've had to look for another internet radio player in the CLI.

After quite a few false starts, I found sonicradio. Not sure why this one isn't talked about more; it's absolutely gorgeous and has all the features you could want. Highly recommend. Wish I'd been using it these last few years instead of radioactive.
