I randomly wanted to find out the highest placed artists that I've only scrobbled one song by:

58 scrobbles - Zac Efron (Rewrite the Stars)

47 - Lea Michele (Cannonball)

45 - A Great Big World (Say Something)

44 - Klingande (Jubel)

42 - Sexyy Red (Fat Juicy & Wet)

41 - The Pogues (Fairytale of New York)

39 - Little Nikki (Little Nikki Says)

33 - Disco Lines (No Broke Boys)

31 - Wizzard (I Wish It Could Be Christmas Everyday)

31 - Prince Royale (Back It Up)

I'm not sure which of those artists I'd be most intrigued to hear a second song by!

https://lastfmlists.com/

Great idea - I've had a look through my most scrobbled, and there are a lot of artists to whom I've given their next most played song 1 scrobble, but the highest with no other scrobbles at all is a song I've just written about in my 2025 EOY, followed by a clutch of my BJSC entries:

25 Ailith - Drought

24 KÄSSY - i-i-i

24 Mirella - Timanttei

24 Yakima Jera - Dertlı Dolap *

23 Hallan - The Colline Gate

*I definitely have listened to other songs of theirs, must have been on youtube

Bobby Helms - Jingle Bell Rock is the first commercial hit to appear, with 21.
