Note: I'm unable to update this for P3 Reload, P6, or any future games simply because of the 500-track limit. If you want the entire series, check out my other two playlists that cover the best of everything in the franchise:
https://soundcloud.com/hexenvexen/sets/best-of-persona (Basically a shortened version of this playlist but also including the PS1 OSTs and P3R)
https://soundcloud.com/hexenvexen/sets/best-of-persona-2 (Music from the spin-offs, anime, albums, concerts, etc)

The OSTs of Persona 1 PSP, Persona 2 Innocent Sin PSP, Persona 2 Eternal Punishment PSP, Persona 3 FES/Portable, Persona 4 Golden, and Persona 5 Royal.

Please note that this playlist only includes the PSP versions of Persona 1 & 2, due to the track limit of 500 placed onto playlists. I've considered updating the playlist to have the PS1 versions instead to keep them consistent with P3, but nothing's been decided.

The tracks exclusive to the updated versions of the games are mixed in with the original tracks. For example, the tracks that are exclusive to Persona 4 Golden are mixed in with the original tracks from Persona 4. I've also removed some of the "fat," such as the 8-bit music or the mini-game music, to meet the track limit.

This playlist is considered finished until SoundCloud expands its playlist limit, so please enjoy!
