I keep an Ipod dock/amp/speaker thingy in the comp trailer and I just hit shuffle and play. I get some weird looks from people walking by. My musical tastes are anything but Rap or Hip/Hop. Takes a mind stretch to go from Mozart to Stone Temple Pilots back to back.
Let's see, Copland, Mozart, Achoustic Alchemy, Alan Parsons, Bach, Beatles, Bela Fleck, Billy Joel, Blood/Sweat & Tears, CCR, Boston, Bruce Hornsby, Chicago, CSN, David Benoit, Dixie Dreggs (bet nobody knows that one), Doobies, Steely Dan, Eagles, EWF, Diana Krall, ELP, Tower of Power, Zappa, JT, Nickel Creek, Pat Matheny, Blink 182, Pink Floyd, Queen, Rush, Sting, Van Halen.... The list goes on and on.
