Hello there,
My name is Mateo.
I dj on tango salons 
Important that I can use 2 playlists.
One for pre-listening
One for playing.
I love the traditional Tangos.
Welcome Mateo, did you know that you have an extra preview player? This allows you to prelisten all tracks in the file archive or in your waitlist. 
Dear Thomas,
Thanks for the reply, bought pro already
Cool, you are welcome to ask your questions here.
