You Know You're In California When...

When you hear Feliz Navidad (you'll hear the pronunciation if you're not from around here) three times in one hour on the radio, you know you're in Southern California or maybe Texas.   Are there other states with such a strong Mexican culture? 

There are all different versions, this one is not the most traditional, but you can get the idea of what it sounds like.  The only Spanish words are the title, perhaps it's a translation.

I, personally, have been listening to the Winter Solstice series during this holiday season.  What have you been listening to?
