If you're listening online through the web browser app, on the bottom left (by the play/stop button, and volume control) it will say
"Commercial Break"
when they are in commercials, so I usually hit Mute when I hear them talking about what's coming up after the break,
then un-Mute when I see those words disappear.
It's not perfect, sometimes I'll catch the last half of a commercial or so, but it's worth it to not take the full brunt of those awful ads.
