It's really kind of an ugly word for what it is. However, I think it fits the vibe of this album, and I like to introduce new vocabulary words whenever possible. I do teach English, after all. For what it's worth, I also enjoy gently busting rhymes (but only sometimes).
Petrichor will soon be able to stream or purchase wherever you get your music. Please do, and if you happen to know anybody else as cool as you, please share my songs with that person, too. We should all hang out sometime.
