How can I get Siri to shuffle all songs by Phish?

Every time I ask Siri to "shuffle all songs by artist Phish" it shuffles all songs by "Real Big Fish" from my collection instead.

Siri seems unable to understand that "fish" and "phish" are phonetically-equivalent.

Putting aside my suspicions that Siri is secretly judging my tastes in music, how can I get Siri to play the correct artist in this specific case?

Put all your Phish in a playlist, and give it a name like 'tunesofish'. Then simply say "shuffle playlist tunesofish". Siri will open the playlist and play it shuffled.

Here, I've asked Siri to play my Comedy playlist:

This works with a smart playlist set to auto-add everything from artist "Phish":

"Hey Siri, shuffle all songs by P H I S H".

Siri will usually let you spell things out, and it works great here.
