HomePod Audio Sources

A week before the HomePod's launch, we now know every way HomePod can be delivered audio [Source: HomePod Tech Specs]. Obviously, there's Apple Music, which lets users stream millions of songs. There's also the user's iTunes library, iCloud Music Library, audiobooks, and podcasts. HomePod also has access to Beats 1, Apple Music's live radio station. Finally, and most importantly, there's AirPlay. This is essentially a digital AUX cable for HomePod, where any outputted audio from a compatible device (i.e. an iPhone) will be streamed to the HomePod. That being said, there is no native third-party support for apps like Spotify. Hopefully, Apple expands this eventually.
