Hi, Dave - I suppose "noise" and distortion might be a better term than "interference." The Bose soundbars are connected directly to my network by WiFi, and do need not go through my computer. They are controlled by my computer or phone, but will keep playing even when the phone or computer are turned off. The sound on Spotify is inconsistent - sometimes it's good and sometimes it's not. But it is consistently good on Amazon music.

So, I'm tempted to switch to Amazon.
