That's "Baby Blue," a Top 20 hit for Badfinger in 1972. Its sudden surge of popularity was related to the song having been featured in the final episode of Breaking Bad, or so I was led to believe. It was off the chart a week later, but the week after that, this turned up:
"The House of the Rising Sun" was a number one hit for The Animals in 1964. Its appearance in the Hot Rock Songs chart was propelled by it being covered by Kaley Cuoco's sister on The Voice the previous week. (An aside: The Voice regularly throws a wrench into the maintenance of my playlist; performances by contestants on the show appear on the chart every so often, and they're never available on Spotify. This week, for example, Cole Vosbury's cover of Passenger's "Let Her Go" is #15; I filled the spot with a live version by Passenger.) Like "Baby Blue," "House" dropped off the chart a week later. This week, the death of Lou Reed propelled this onto the chart, 40 years after it peaked at #16 on the Billboard Hot 100:
It'll be gone next week, I suspect. We'll be seeing Elvis Presley up there one of these days, I'm sure.
