It's not mislabeled, it's a cover of 'Drift Away' by the Doobie Brothers and I've heard it before, although I remember the Dobie Gray version best, like you.
I did learn something interesting today, though: Dobie Gray's version wasn't the original; it was first recorded by someone named John Henry Kurtz in 1973. Who was he? No idea, but here is the original.
Oh, and by the way, it is written by Mentor Williams, younger brother of the famous songwriter Paul Williams [Just an Old Fashioned Love Song, Rainy Days and Mondays, Evergreen, We've Only Just Begun]. Interesting
