Podcast ideas?

I am still a little unsure about what to do my podcast on. I am hoping to go with something a little more fun than "serious." There is a possibility that I may do one on new and upcoming music artists - i have a few friends that are in the process of working their way up in the music industry, and it might be fun to talk about the new bands.
Or, in light of the holiday season, it might be fun to do an interview with a guy and a girl about shopping for each other - that can sometimes be a really funny conversation. We all know how many difficulties and anxieties come about when all this comes around.
OR, if I lean towards "serious" I may discuss women's rights and the political issues that have recently been on the rise.
