Multi-threading is not a common topic among web developers, yet today I decided to give it a shot in bash to download and convert to mp3 my favorite ambient music station by Mike G I like to listen to while programing. Problem is, each session is 2 hours so I would like to bookmark sections I like most using Amarok but it does not play well with aac sources. So how do I get the whole 32 part archive and convert each one to mp3 in the most efficient manner?
