I discovered a new podcast earlier this week. Metalcast is a weekly podcast full of awesome metal tunes. Each episode is between 45 minutes to an hour long, and features some of my favorite songs, and great new songs I'd never heard before. Many of the episodes have a theme, for example songs from soundtracks, or bands with female lead singers.
The most recent episode, 69 is of course all about sex. After listening to it I looked at their back catalog and discovered episode 31. All about Tolkien!! Songs inspired by his books, or by bands who's names were inspired by his writing. So my fellow metalheads, definitely check this one out :)
