Something to me that makes them irritating is that, so, okay, we're getting extended episodes lately, right? But we're only getting around 50 minutes of actual show, it's just stretched to 80 minutes with a fuckton of commercials. The average episode would be somewhere around 45 minutes, so the "extra" content is around 5 minutes per episode. The songs take up roughly 3, so we're only getting about 2 minutes of actual plot-driving content (and before someone argues that the singing the other night was plot driving by summoning the dude, well, sure, but it didn't need to last the full song in that case, did it?). I'd be more than willing to give up those songs if it meant there weren't 30 minutes of ads interspersed throughout, the commercial breaks are insane (and I watch AMC for fuck's sake, a place where I've seen episodes of TWD get ~2 minutes of show followed by 3 minutes of ads.)
I don't "mind" them, but when you view it as screentime that could be really adding to the story, moving it along, developing the characters better, etc., it starts to feel wasted. It's every single episode so far. If it was once every few, that'd be very different for me as a viewer. Considering almost every single season so far that I can remember has had a rush of the final few episodes to resolve everything, resulting in a narrative clusterfuck because they spent a lot of time not getting there at random points earlier on, I'd love to see the extra time given actually go towards driving this thing forward so that the pacing feels consistent and not shifting from 5 to 50 miles an hour at the tail end.
