I mean, she's 20. Carly Rae Jepsen was 27 when she released Call Me Maybe in 2012. It's been a decade since then. Her life has changed considerably. Billie Eilish has only been around for a hot minute, she's likely still establishing what kind of artist she wants to be. She may change, she may not. She's got literally decades to figure it out.

Artists will work on what interests them. If they want to go more down that route, they will. If they don't, they won't. Again, it does feel like more of those self-established expectations that you set on your initial assessment of Billie Eilish.

Music is a present art form. It's not describing who an artist was or will be (though those topics can be broached in the art form). It's music created by them now, for now, as they are now. Sometimes it's fine to take things at face value. You don't have to enjoy everything, you don't have to relate to everything and you don't have to even get everything (I still don't really get Enya). Things get popular with some people because they just happened to get popular with them. It was the right thing at the right time for the right people. Like Heaven is a Half-Pipe by OPM.
