I just gave the whole playlist a listen. To me, Petrichor by Brambles comes the closest to remind me of "rainy smells". Most of the songs that are guitar-heavy or have lyrics completely ruin the sensation (not saying the songs are bad bc of that reason).

some context: I can pretty much always smell rain when I hear rain, so music that contains actual rain will come the closest to triggering the same sensation. However, sounds that mimic the bliss and murkiness of a rainy afternoon also has the same effect - e.g. bells, piano, roomy reverb, "pitter patter" percussion etc.
