Well,Ah, that word, listenable -- all it means is :
'music I can stand to listen to'.
So?
It just means that with (most) modern music, produced and performed after 2000 or thereabouts, (exceptions apply of course) i can't stand to listen to, that's all.
Unfortunately at my daily work i'm not the one controlling the radio or music stream, so mostly WE, (not just me) have to endure the same typical mind numbing crap.
Luckily after more than one complaint from several people they vary a bit more lately and turned the volume down, so that it is somewhat bearable now.
That's not to say that if they would play my (kind) of music all day, other people wouldn't complain, i think they would, very fast
