Finally ready for release, it's my first pack! That doubles as a disclaimer, as the chart quality ranges from "literally first chart I ever made" to "know what I'm doing (ish)". In the spoiler below is the song list, with a short description of the expert charts.
There's no real theme to the pack. Songs range from techno to slow waltz to bossa-nova, reggae, ragtime, video game music, rap, 8 bit, opera, Touhou... pretty much a mostly random collection of everything!
