The follwing is my working document as I create a pipeline for faster YouTube > LibSyn / iTunes distribution. This is not complete, but really cuts down on some time.

➜ youtube-dl --extract-audio --audio-format mp3 YOUTUBE_ID Example output:

Deleting original file 74 - FirefoxOS & JanOS-4sZn_dTnhv0.webm (pass -k to keep)Concating the intro can really cut down on work, because the intro can contain the base id3v2.4 frames and that flows to the final output.
