9. Aqualung - "Strange And Beautiful (I'll Put A Spell On You)"
https://www.youtube.com/watch?v=16AWcaERD6I This is just the first of many stalker-ish love songs on this list, and it's one of the most subdued examples. (So strap yourself in.) It's not just the hauntingly mesmerizing piano melody and disconnected vocalization that makes this ballad seem a bit off. There's also the matter of these Disney villain-esque lyrics:
You'll fall asleep when I put a spell on you And when I wake you, I'll be the first thing you see And you'll realize that you love me
To be fair, those lines are almost directly copy and pasted from Shakespeare's A Midsummer Night's Dream, but given good ol' Will's track record with ending love stories in the worst way possible, that doesn't excuse the creepiness here.
