So just to clarify, yes I'm listening to both tracks in my headphones. For example, when I can use the speakers, I would have track A playing through them "to the audience" , also have both tracks playing in my headphones, and then when I´m happy i´ve got track b ready to be introduced, I take my headphones off altogether and make any (hopefully minor) adjustments. I just had to think to myself, when I was out and recognized what the other dj´s were doing, why don´t I do that? I guess it´s a different ball game playing out and about. Hope I didn´t confuse anyone too much! Thanks for ill the replies
