Polypropylene Capacitors with Polarity?

Is polarity on these newer caps a valid concern and a benefit to test them and install the "correct" way?

Thanks,
Rich

I have heard it said that this can be an issue and have read how to use a capacitor tester to determine the outer foil. The article stated that the outer foil should always go to the ground or to the low side of the signal. The article was in an audio magazine and audiophiles can have some peculiar ideas. I did try their method and never discovered a spec of difference.
