As a metal fan, iam proud of our beloved genre, so getting a none metal listener to listen and appreciate the musical journey often puts a smile in my face.. so thus cranking up an album or two in the office could shatter some barriers and open up some ears. Usually i mixed it up from doom to ballad thrash, goth to experimentel, death to acoustics, and somtimes to string in some danceble metal tunes so they don't immediately shout to turn my speaker off. so far i had a results but not that many.. buts still cool.
