Pixeltunes has a lot to like, but it's not for everyone. Your enjoyment will depend on whether you like video game music, whether you like the hosts' sense of humor, and whether you like their banter. I love video game music. I used to be iffy on their banter, but they’ve really improved in the last year.... especially when it comes to stating their opinions on tracks they don’t both like. I can't play the show when my kids are around, due to the lowbrow content. But they’re usually at least somewhat funny, and sometimes hilarious.
I do like their enthusiasm for games, and they do go really in-depth in their research for each show; they're not regurgitating Wiki pages here. They also play a lot of obscure arcade, import, and computer games you've probably never listened to(Sharp X6800, anyone?).
In any case, the show is well worth your time.
