Before “Crazy Little Thing Called Love,” Queen only had two top-10 US hits: The lyrics, for instance, are virtual gibberish. We learn that love swings, jives, and shakes all over like aThis thing called love I just can't handle it this thing called love I must get round to it I ain't ready Crazy little thing called love This (This Thing) called love
As for Crazy Little Thing Called Love, it's what's called a pastiche. It's supposed to sound like an old rockabilly-era song. It's intentionally similar to old Elvis songs like All Shook Up or Don't Be Cruel, and it stands out when Queen does it because (unlike, say, The Stray Cats) that retro stuff wasn't their usual sound, so it's really easy
