SIRI doesn't play the correct songs I tell it to in iTunes. I asked to the play the album "Zooropa" by U2 in my music library. It played a different U2 album. I asked it to play the first song on the album "Zooropa" by U2, and played a different song. I then asked it to play the song "Zooropa" by U2, and it played a completely different song ("Volcano", which doesn't even sound close).
Given that Siri is mediocre on the iPhone, I was hoping it would work better on a computer with a faster processor (Mac Mini 2015). No dice. Looks like we're back in the early 1990s for Apple, headed towards the 1997 abyss, except there's no Steve Jobs to course correct.
