How can I "count in" or delay a song?

Hi Folks,

I use DJay Pro (windows) and DJay 2 (android) for an unconventional reason. I am not a DJ, but rather a keyboardist.

I use these products to slow spotify songs down, so i can figure them out, and play along more slowly as i learn.

Can you suggest an easy way for me to “count in” a song or even just delay it a few seconds before it starts. I need to get my hands in position after i hit play.

thanks
