Just listened to all three albums in a row and I highly disagree with the idea that they are sonically or thematically identical. There is absolutely a clear progression and it's beautiful.
Well the ballads are more pop but there's a pretty equal balance of alternative/indie/pop on all 3 albums, I think.
IA.
Tbh I think what I miss from her is the folkish vibe she had in her first album. She progressively got more general indie pop and I don't hear that 'Swedish' sound anymore (maybe because she started to use less cohesive instruments as well). But regardless INL is a nice album.
