Spotification

I’ve had a free spotify account for some time now, and I’ve used it actually mostly to listen to music that I already own, so good is the client. So when Spotify announced they’d be limiting you to 5 plays per track, and a maximum of 10 hours per month, I was a bit sad about that.

What was more irritating was that much of the music I’ve already got is sitting on CD in lofts in buildings where I’m currently not. Much of it is also on YouTube of course, but it’s not as pleasant to access.

What to do? Well, it’s well known that Audio Hijack Pro can rip the audio from Spotify. But who wants one giant 10-hour MP3 to deal with?

Sitting around with some time on my hands due to a broken hip, I cobbled together a script when I found that groovy was capable of invoking AppleScript scripts. Taking 240mg of codeine / day was not a time to start learning how AppleScript does file handing; this is all pretty hacky stuff and could be improved on, I’m sure. Think of it as proof of concept.

Steps:

1) Get groovy installed

2) Turn the debug logging on in growl

3) Start hijacking in Audio Hijack Pro

4) run the following script (e.g in groovyConsole)

5) Play music

The script will tag the music you play, and split into individual files. It probably won’t be happy with things like “s in track names, but fixing that is left as an exercise for the reader. Please bear in mind this was written literally on drugs.
