I'm finding that while Siri understands all by commands and says they are being performed, not all of them are.
E.g.
"Play Tom Jones" says it will play popular songs from Tom Jones and it does.
"Play Imagine Dragons" says it will play popular songs from Imagine Dragons, but then nothing happens.
It's like Siri understands the command, but doesn't always send it to the Music app.
Are other people having this happen?
