Why can you understand Spotify not working on IPv6?  Are they known
for having a generally shoddy product?

Pandora works fine on my IPv6-only NAT64/DNS64 setup.  As does Youtube
and many other multimedia services.

Is Waze much different from Google Maps?  Google Maps works great, as
does Mapquest on ipv6-only

And this is the conversation folks will have...: "Oh... Waze does not
work, you should try their competitor it works great"  and " I used to
use Spotify, then i changed networks and it stopped working... now i
use Pandora or Google Music"

Yes, 85% of the Android apps i have tested (sample of over 200) work
fine on IPv6-only ... likely due to just good coding practices ... not
due to specific IPv6 engineering.
