Sorry, I can't help, but just to add that I also find Alexa, at time pretty dumb when it comes to any understanding of what I have asked for.
She/It either gets the name totally wrong, or can't find it, unless I ask in a specific way, either the artist first or the album first, or the track, or I have at time given up as she find nothing, but "play songs by *the artist*" then magically finds some.
It's annoying as if I say the same works to my PC in either Cortana or Google, they both recognize my request dead on almost 100% of the time.
I speak, I think pretty clear southern English without any accent really, so would of thought my voice should be easy to get right compared to some.
they really need to improve this. esp if the google home comes out in the UK and it's far more accurate
