When I was working, I'd do almost all my modeling in the evening. Usually when I model in the evening, I'd have heavy metal on--anything from classic Led Zeppelin, Black Sabbath and Deep Purple all the way through AC/DC, Metallica, Motorhead, even some of the "hair metal" like Britny Fox or Def Leppard, the Seattle bands like Nirvana or Alice In Chains, some of today's "nu metal" bands like System of a Down if I can get them on vinyl LP. (Of course this means having to stop every twenty minutes to change the record, but I'm one of those vinyl fanatics that hates the sound of CD's.) While modeling during the daytime, I like other kinds of music--Neil Young, Pink Floyd, Dionne Warwick's "Soulful" album (the greatest non-metal album ever made), INXS, The Cars. Other times I might listen to talk radio ( Jim Rome is a favorite of mine).
Now that I'm not working, I find that lately, I've been doing more of my modeling with the music off. It's too distracting sometimes with all the great stuff in my record collection! Conversely, more often I don't model while I listen to music; now I just kick back and enjoy!
