I really liked how the music was split up like this then if you picked a genre it went even further to be more specific to what you are looking for.
I wanted it to be a clear mashup so I used a classical low energy song and a rock high energy song.
I used audacity and put the two together.
You can see that the classical song is the top bar, the wave lengths are smaller whereas the rock song has high wavelengths. Some how despite the difference in types of mysic I actually really like how this turned out. The classical song made it sound more fuller and I really like it!
Below is my final product.
