If there was a holiday associated with honoring veggie tales...then more power to you. To do it "just because" is a bit of a stretch though. We're talking 3-4 weeks out of the year, during the biggest holiday of the year here. It's SUPPOSED to be festive outdoors.
I guess you would have to define "blaring". If you are going through all the effort to produce outdoor Christmas music then you want it to be loud enough to be heard by people and cars walking or driving by...otherwise there's no point. If that's considered "blaring" then I think you'd need to get over it as long as he shuts it down early enough.
If it's to the point the bass is rattling your neighbors windows...then yeah you have a point and he should turn it down a smidge.
If it's just to the point where you can hear it in your house next door...again I say get over it and enjoy the free Christmas music. Just means you don't have to turn it on in your home! Think of it as saving you on your electric bill .
