@Freshfluke:
Music is a hard (to carry) business :-)
When i remember the first years od DJing, i carried about 200 pieces of Vinyl and nearly 300 CD's, Mixer, turntables, CD-Players...
And in the end there was no gig i was not missing one or two cd's.
Thank god for the invention of digital DJing (and Fraunhofer for inventing MP3)!
