More earworms

Only in my brain, I think, would it be possible to have these earworms all in my head at the same time:

• A Richard Thompson remake of, of all things, a Britney Spears song that I barely knew until I heard him sing it twice on repeats of “Fresh Air” this weekend. (And I’m not a Richard Thompson fan, either.)
• “Thank You For The Music,” not because he played it, but because in speaking about the Britney Spears song, Thompson likened it to Swedish pop, very much in the vein of “Abber,” as he pronounced it (and now he’s got my wife doing the same, just to annoy me). An ABBA earworm is never a bad thing, for me, but that one is very odd and I’m not sure how I got to it. (Along with this earworm, I keep having to try to work out in my head whether it was Frida or Agnetha who skipped the big ABBA reunion at a staging of “Mamma Mia” in the Ovation TV special. There could be almost no information that I need less, and yet here I am, trying desperately to remember it so I can put the question out of my head.)
• “My Baby Loves Sad Songs,” a relatively obscure Boyce & Hart number, but at least I know how I got there: flipped from the awful Richard Thompson song to the ’60s channel and got caught up in The Monkees’ “Valleri,” a perfect little Boyce & Hart confection that for reasons I’m not musically astute enough to explain reminded me of “Sad Songs.” Which one’s Boyce and which one’s Hart?
