I'm always hearing songs that are like other songs and

Seeing things that are like other things. Or people.
Just thought I'd let you know, in as much as Bob Dylan has released a new album and his picture is on Rolling Stone, that Mr. Dylan is looking very much like the actor Richard Boone these days. Well, not much like Richard Boone right now, given that he died in 1981, but like Richard Boone as he looked in say, the 1970s.

Some people's looks move in nearly parallel lines, looking like and then not looking like each other. I just finished reading The Woman in White by Wilkie Collins. One of the characters in that story looked very like another character, and it became a plot point. Also, a library I worked at had a patron that looked like Harrison Ford for a few years. Nevertheless, as he grew older, he began to age differently than Mr. Ford.

In Bob Dylan's case, it's been just the opposite: I never would have confused him with Richard Boone until just now.
