you guys seriously still use mp3s with the amount of space that is available with modern mass storage devices..... dont you want to show respect to the artist and their music, by playing the best quality of their music possible?

I have been playing for 1 record label for over 6 years and that label has approx 32G of music in wav that i know inside out.
i also play for another label that has about 16G of music in wav
then i also like to play other music from my collection when the crowd is looking for something else.
these different styles i keep categorized and separated in different sticks. just like i used to keep different styles in different crates.
so 1 port doesn't work for djs like myself that need to swap sticks.
every1 is different
