Um so ein teurer Wein zu sein, müsste er wirklich besser schmecken als dieser da.

The audio is pronouncing the “ü” in müsste long, and I’m pretty sure this is supposed to be short, both because I’ve heard this word a lot and because of the spelling/pronunciation rules (followed by a double consonant = short). Forvo and Google translate both agree.

It looks like the audio has been corrected! Yay.
