If you bought a love potion to cure your problem of being “A flop with chicks”, would you expect it to make you more attractive to women, or would you expect it to make everything seem attractive to you? I would expect the former, but the “love potion” in the song did the latter (and had predictably bad results).

I know. I expect too much logical consistency from songs. But does this
make any sense?

I still think the song is nice to listen to.
