You get a chance to go back in time with all the current musical knowledge of the 20th/21st century.

For instance, you can bring Jazz back to the 19th century, but you will have actual musicians arrange your music for you(if you need it). Regardless of that, you can use the lyrics of the artists of the 20th/21st century.

What style would you bring through the time machine?

I'd bring back some New Jack Swing to the Romantic Era of European music. [Imagines an orchestral arrangement of Jodeci's "Stay"]. Or a Symphonic version of "If I Ever Fall In Love"...
