So I wasn’t content with just one way<\/a> of creating M3U playlists out of iTunes. I went and wrote another. There’s more than one way to do it, as I learned writing Perl programs.<\/p>\n

Pity I’m writing in Python.<\/p>\n

Anyway, this method only works on a Mac, because it uses Applescript. Actually, it uses appscript<\/a>, an event bridge that lets you do what Applescript does, only in a real language like Python. It’s called iTunesm3u.py<\/a>, and requires that you install py-appscript<\/a> first. To use it, have iTunes open. Select a playlist. Then run the script (or double-click the script if you turn it into an app with py2app<\/a>) and it’ll create an .m3u file in the same directory as the script.<\/p>\n
