Those are all…some songs. He’s worked with Weezer and Sebastian Bach too!
Let’s stipulate that he writes workmanlike top 40s fare. I try very hard to appreciate craft, even in music that I don’t necessarily like. But that is really a bunch of garbage. Some of the worst hits of the past 50 years or so.
the dude can supply radio-friendly mass-consumable rock-flavored audio product.
i found that while i was trying to see if any of Joan Jett’s hits were originals. and the answer there is: she has co-writing credit on a couple of them; but most are covers.
It doesn’t matter. My 13yo self will always be in love with her.
