there was a point like 15-20 years ago where me and a couple friends were listening to a bunch of songs backwards just to see how that was and barbie girl reversed always stuck out at me as particularly good. it gets real beautiful imo and part of me always wanted to record some reverse covers like this, but changing the instrumentation and lyrics so it all plays forward, not the vwoop zwook hwoop backwards drums etc, just do the backwards structure so it just sounds like a regular ass song but weirdly familiar. the reverse melody is still stuck in my head to this day
