I'm not familiar with Springsteen either
Have never listened to one of his albums in full- friends have tried to play me "Nebraska" and other shit by him I've forced them to turn it off. So maybe that wasn't the best comparison but my point was that the worst Dylan I've heard just sounds dull and relatively generic rather than jaw droppingly awful. Though I might be whistling a different tune after listening to "Saved".
I guess I can see the Dire Straits comparison (pretty unfamiliar with them as well though) just based on "Gotta Serve Somebody", the only song I really remember from "Slow Train" (partly because it's on a hits comp I own). And FTR I think that's basically a decent song, if a bit cheesy and gimmicky.
