Thanks for reporting these, @tommywimmer.
I'll make sure to let our curation team know so they can further investigate. 🔎
I'm following up with my request. I have created radio stations based on each of these songs, and I'm still getting the wrong genres played.
@tommywimmer Our curation team is still looking into your initial report.
Thanks again for your patience with this!
