You should be able to say "Hey Siri, listen carefully" brief pause "isle ... of ... dogs", or some such to have the device enter a special mode where it attempts to identify individual words more accurately.
Without a special mode, you'd likely say "Hey, Siri, play Isle..." "Okay, I found--" "Dammit, Siri, I wasn't done!"
Yep, tried that too... but admittedly the sound very similar. I keep getting "I'll of dogs" and "I love dogs".
