Thanks for the file, MuffinMan
The music is relatively loud.
A great deal can be removed by isolating the center but not all and what’s left has some artefacts.
The idea is of course to mix in your own music afterwards or to be content with a gentler setting that leaves more background but less artefacts.
First, the used tool:
I’ve applied “Center isolation” with the most extreme “Strength” setting.
The file has afterwards to be amplified (that’s normal with such high settings).

Place the tool in your plug-in folder and restart Audacity, if you want to try it out (Vocal Reduction and Isolation).
Important:
Works only with Audacity 2.1.0 or higher.
Here’s a sample file with alternating original/isolated center:
You can of course preprocess the wave file with e.g.
- Expander/noise gate
- noise reduction (with strings only profile, if you find a part with music only)
- equalization and spectral selection (look in the spectrogram for long lasting frequencies)
I hope this helps.
