I mean I'd argue that she pushed the button an awful lot on the second album, and in terms of "growing up" we'd already had Live To Tell at this point, but nevertheless, it's a 10/10 song.
It's hard to still truly get an 80s feeling from Madonna songs now because i have listened to them so much over so many different eras, but this song evokes a lot of very specific memories for me - particularly the opening strings. It's also probably my first strong memory of Madonna - before this point I knew most of the hits but didn't really follow her as an artist or associate the songs with her. But I remember seeing the video for this on TV, and it seemed to be everywhere for a minute.
