Should Siri on Home Pod recognize the name of a playlist suggested by Apple Music

Just got a Home Pod and am testing out Apple Music. In browsing Playlists suggested by Apple Music I found one titled Classic Rock which I wanted to play. So I asked Siri to play playlist Classic Rock. I got Beethoven classical music. So I tried play Classic Rock and Siri played Classic Rock Essentials.

I have had success getting Siri to play my playlists, and asking for general content that Siri then finds some content to play (e.g. Smooth Jazz). So I thought this should work.

My questions are:

1. Should I expect that Siri will recognize the name of a playlist that Apple Music has suggested for me?
2. Is there a special syntax I should be using?
3. Is there a way to ask Siri questions to figure out what it knows?

Thanks
