Viennese Music?

I will never forget an early dance teacher training class when we were to choose the dance to the song - "What a Wonderful World". The fellow I was partnered with and I decided Viennese waltz.
No, Silly! Slow Dance, what Mary called One-step and Arthur Murray called Foxy.
But I see that type of music chosen as Viennese on DWTS all the time, for instance the gorgeous Ray La Montaigne songs "Hold on Forever" and "Trouble"
Traditional Viennese has an oom-pah-pah feeling while this will be very smooth. Gotta try it out.
