It seems that it took iTunes about week to get Episode 37 up on the feed. It seems that there is an issue with the date on the podcast. On the RSS page, the date of ep 37 is April 11. According to iTunes, it’s March 11. Right now, there’s no fix for that because it’s something on iTunes side.
Epidode 38 should hit the feed Wednesday/Thursday. If it doesn’t hit the iTunes feed, just copy/paste the the RSS url (http://feeds.feedburner.com/AnimeJamSession) into iTunes and all should be fixed. 🙂
