Mainly 1958-1993 Rock 'n Roll (ranging from: soft rock [eg. Simon and Garfunkel] to blues rock [eg. Chuck Berry], to heavy metal [eg. Metallica]), some Funk/Soul [eg. The Ohio Players], Retro Pop [Genesis], and a tiny bit of Disco [eg. Bee Gees], Modern Pop and Rock [eg. The Black Keys], Country, and Instrumentals.
I updated regularly since 2017. Hard rock is the most common subgenre. Many songs will probably familiar, many others are ones you wished to have heard earlier. It is a positive playlist and a good for escapism. I listen to it with Soundmagic E-11C's.
