At one point or another, I've owned every album from "Shot of Love" all the way back through to the original "Bob Dylan". I guess that means i made the man rich - "All I really want to do, is baby sell records to you".
As for Slow Train, I didn't really like that period music in his career. As in all Dylan songs, things are either good or their evil, right or wrong - which side are you on. Preachy, moralistic ditties, that tend to contradict both earlier and later works of the same artist.
Personally I prefer the stuff that Dylan's done in the last few years to his saved period. I gather that Dylan is not nearly so sure of his salvation these days, but is quite cognizant of his mortality and limitations.
