Shinji's Walkman (I don't know the exact term in English, but I already know it's a rare cassette player that didn't take off except in Japan), but what I'm interested is the music he is listening on it. (More specifically, the cassette have 26 tracks, and a duration of around 1h30 if I trust my memory of the appearance of the player). I've re-watched NGE and the RoE:1.01, and the music have a great importance on Shinji's development, but we do not hear enough for any app to recognize it, and the name don't seems to be revealed in the credits.
Did the name of the cassette/compilation/music Shinji is listening to revealed in the show, a interview or any other "official" source?
