I got to confess something: I love Muxtape! Did you know there is a userscript which lets you download the songs? It’s not encouraged though…
I’ve been trying to learn Shell Scripting. So I decided: why not make a Muxtape downloader. This is my first shell script (longer than a few lines). I’ve thrown together code I found at various site, and I find programming with bash… special. Currently: the script looks like this:

Yuck! But it works, save it in script.sh, make it executable and then ./script.sh muxtape_username.
This will save all mp3s. It took me an hour to figure this out, and I’m sure lots of you could do this much better. Still, it was cool to build… but in Perl or PHP I could’ve done this much quicker and cleaner. Oh and by the way: don’t abuse this… Muxtape are friendly people.
