This week we turn the mics on ourselves, kind of. Lars Wikman joins the show to give us a guided tour through ID3 esoterica and the shiny new open source Elixir library he developed for us. We talk about what ID3 is, its many versions, what it aims to be and specification-and-speculation.html">what it could have been, how our library project got started, all the unique features and failed dreams of the ID3v2 spec, how ID3v2 and Podcasting 2.0 are solving the problem differently, and how all of this maps back to us giving you (our listeners) a better experience while listening to our shows.
