I have said that I will not play a random device brought to me to suffice a momentary urge for their favorite song etc. I had an issue long ago which has kept me from entrusting my reputation with a file or disc or whatever I havent had proper time to QC at an event. The groom actually slipped me a disc to play and dedicate to his mother in law. Anyone know a song called Freaks Of The Industry? Yeah I played the first minute of it I was pulling vinyl and realized the song was really bad I turned ejected and smashed the disc right in front of everyone and then apologized profusely to the mother and others the rest of the night. I most likely didnt gain a referral on that one. This was in Pasadena California in 1989. I will not touch another random unit or disc during an event unless proper revue has been done.
