Enigmarch, Day 6: ROUND

Somehow my mind went to music, but not rounds: "Round Here" by Counting Crows, that kind of thing.

Is this solvable? Honestly I have no idea.

Singing Rounds

Here are some songs (with the year they first charted in the top 20 of Billboard's Hot 100). The numbers in parentheses are the length of the answer and the index, separated by a slash, and because I'm bad at counting I checked them all programmatically. Oh, though as you can see from the clues, there's been some rounding.

1992: Jump Ao (11)

1963: I Wanna Be Ao (2)

1978: I Love The Nightlife (Disco 'O) (1)

1995: Run-Ao (2)

2006: What Goes Ao...Comes Ao (3)

1981: Turn Your Love Ao (12)

1985: Don't Come Ao Here No More (2)

1972: You Don't Mess Ao With Jim (4)

1982: Love Will Turn You Ao (1)

1964: I Get Ao (2)

1984: Wrapped Ao Your Finger (1)

1960: Rockin' Ao The Christmas Tree (5)

1985: Fortress Ao Your Heart (1)

1985: You Spin Me O (Like A Record) (2)
