Those Thingies That Play Sound

ZOMG, so here's the tea on what OnSong does when you throw MP3s at it. Basically, if your MP3 is fancy enough to have lyrics already baked in, OnSong gets all ambitious & creates a whole chord chart situation based on the song's vibes & lyrical genius.

Then—plot twist—that MP3 gets yeeted into the OnSong audio media library & totes optionally gets paired up with the chord chart it just made. Which means you can finally ditch iTunes & stop pretending you understand how to sync stuff. Literally just let OnSong do the heavy liftin'. You're welcome. 🎉
