I went to this get to together once and there was the DJ standing over a laptop, at one point he was taking request from the patrons and by the time he is finished talking to them, the music is already live. He had like thousands of songs. He did some awesome mixes too.

I never thought of it that way I guess. You would certainly speed up requests, by simply being able to search for them on the laptop instead of going through your library. You could carry more to each venue, and not have the same storage issues.

Maybe I have been a little harsh about this.
