Many thanx yak. Return of audio ads since release of new web player has been a major pain. Dunno how u figured it out but this filter seems to be working great, hope it lasts.
That filter works for most people, but not all. The following filter comes straight from Michael Gundlach, who told us that it works in all cases he's found:
Since adding the "/mp3-ad/*$domain=open.spotify.com" filter noticed Spotify web player stopped playing after one (or two) songs. Also "Oops, something went wrong..." banner between songs had disappeared. Deleted that filter, now just relying on "/mp3-ad/*" filter in Easylist as mapx notes. Non-stop behavior has resumed along with Oops banner (which of course disappears within a few seconds)
