Apple has updated the HomePod Tech Specs Page with Audio Sources

• Apple Music
• iTunes Music Purchases
• iCloud Music Library with an Apple Music or iTunes Match subscription
• Beats 1 Live Radio
• Podcasts
• AirPlay other content to HomePod from iPhone, iPad, iPod touch, Apple TV, and Mac

A lot of people were questioning whether or not it would play iTunes Music Purchases and the iTunes Match music library. I’m glad it does. I suspect the reference to “Podcasts” will just be those through Apple’s native Podcasts app. If I’m going to want to stream Overcast or Thunderscape to the HomePod, I’ll need AirPlay.

The biggest question remaining in my mind is exactly how good the audio quality is for this new computer controlled speaker. I’ll find out in a week.
