my brother-in-law asked me to dj his wife's 40th b-day party in 2 weeks. Since I have the equipment and I'm free he decided to go with me instead of a guy I put him in touch with. Do any of you guys know of any decent free dj software. I'm looking to bring my laptop and 60 gigs of music and just play. I don't want there to be a gap inbetween songs. So is there one that will fade 1 song into the next seamlessly.
