Beato expecting to find "good" lyrics (or music for that matter) in the stuff most popular these days is akin to him expecting to find good food at a fast food restaurant. Kids listen to whatever music they are fed, and eat fast food regularly. Doesn’t mean we have to, and to worry about it like he does seems like a waste of my precious remaining time on Earth. If he thinks the video will make him some money, good for him.
Beato has a deep technical understanding of music, but I find that musical education has greatly affected his tastes in same. He knows a lot more music theory than do many songwriters I could name, but he hasn’t written any songs as good as those writers have. I’m sure he likes Steely Dan far more than Hank Williams and Merle Haggard, and has never heard anything by Iris DeMent. Merle liked Iris’ song "No Time To Cry" so much he recorded it himself. I’ll bet Dylan finds more wisdom in Hank’s "I’ll Never Get Out Of This World Alive" than he does in any Steely Dan song, but I’m not going to fault Beato for not doing the same.
As others have already here said, there are plenty of songwriters, singers, and musicians currently making music as good as is true of every past decade. Lucky me (and others here), my taste runs to music now known as Americana, and there is so much coming out in that genre (Americana is more accurately viewed as an umbrella term for music made by those in the Singer-Songwriter, Folk, Country, Alt-Country, Hillbilly, Bluegrass, Rockabilly, etc. genres) that I have trouble keeping up with it all.
