I moved it the last time. The main reason for me is to get discussions out of idle chatter. If something fits vaguely or technically somewhere else I would prefer it goes there than fitting it all in this extremely general category.
Real life soundtracks is justified not just because its something that you listen to during your daily activities but to me its more the universal experience that its something you listen to on your portable audio device. Who cares whether it's music or not, it's not like we will suddenly be inundated with a million threads for different podcasts. It's just a general grouping for things we listen to.
But the main reason is to get things out of idle chatter. This is also why I have suggested in the past that sports discussion be moved to The Small Screen. It is mainly a TV watching experience, the Superbowl, Olympics,etc. are huge episodic TV events no different than Cheers. We may get into some trouble with things like video games but i think that's too interactive to be thought of as a TV experience (and can also be PC/portable), as well as current news/world events as they are things of actual consequence that can be left in general discussion.
To be honest the last couple of things probably could use their own forum but we've got enough as it is, and they will have to make do with their best fit,. I just wish it wasn't always idle chatter.
