I'd say it's mostly volume in your example (because there is nothing offensive about Flintstones or country western but volume), but it's content as a general rule. If your neighbor's music consists of "me so horny die bitch die", then it doesn't need to be loud to be offensive at least for some folks. See my example with condom distribution near a church.

Okay, no volume. My neighbor has a hemomgous porn collection. He's told me about it. He's a creep. Now are we still concerned with the substance of his "violation"?
