Greetings DJ,

in this tutorial you will learn how to beatmix tracks and use the special functions in MP3 Tunes.
Even if you are an experienced DJ it's advisable to read some things here.

Beatmixing is the kind of switching between two songs, when their beats are exactly synchronized.
Most of the time, when the beats are in sync, you leave the songs playing together for several seconds and do a very gradual fade between them, so the audience has the impression that the beat of the one song continues into the other, or that the songs are joined together.

For a long time, the ability to do Beatmixing was considered the main criterion for a club DJ. Admittedly, doing Beatmixing with only two turntables and no other help is not an easy task.
MP3 Tunes is the electronical way for this.
To do Beatmixing, you should first select the appropriate songs. (Not all songs lend themselves to Beatmixing).

Then you need to find the Beats.
