Twitch (and YouTube currently) switches to a new content stream to play an ad, which is easy to detect and block in an extension. If I understand the tech correctly, server side ads would be stitched into the playing content stream. The extension would have to know the content of the video to know that an ad is playing. There are some clever ways that might be caught (looking for spikes in bitrate, volume differences, etc), but none of that currently exists in the software in the OP.
Hand of Juno just released their first album, Psychotic Banana, and I’ve been binging it for a solid two weeks. Good mix of heavy and melodic, and good variation between songs. Got its hooks in me.
I will say, some songs are different enough that they almost sound like different artists, so if you check them out it’s worth trying a few tracks. “Polline” and “Destroy the Line” are my favorite heavy songs. “The One”, “We’ve Built the Line”, and “Not a Game” are my favorites on the melodic side.
