Today, SoundCloud CEO Kerry Trainor announced at Amsterdam Dance Event that DJs will soon be able to mix and perform by streaming material from SoundCloud’s catalog within DJ softwares. Traditionally, DJs that perform using digital music download their content ahead of time and mix from that library of songs.

For the integration, SoundCloud is partnering with several companies that offer software used by DJs to perform, including Native Instruments (Traktor), Serato, Virtual DJ, DEX 3, Mixvibes, and DJuced / Hercules.
