The title of an article, "Wis. man cited for 'rocking out' to John Denver" (http://www.msnbc.msn.com/id/34925191/ns/local_news-minneapolisst_paul_mn/) seems to imply that this fellow was cited for listening to the music of John Denver. In reality, the issue is not the type of music this individual was "rocking out" to, rather that he was being disruptive to his neighbor.
Remember that when living in an apartment or townhome setting with shared walls, it is never appropriate to play music or the television so loud as it reaches your neighbors.
