What are some singers/bands that you have everything or as close to everything as you can by? Name no more than ten. Here is mine
Elvis Presley James Brown Otis Redding Hank Williams Sr. Led Zeppelin Jimi Hendrix Robert Johnson Rolling Stones Johnny Cash Iron Maiden
Many more, but I have to follow my own rules.
It's video game soundtracks for Falcom games (Japanese dev). They are fantastic though. Half the reason to play Falcom games.
