NEPU1-BNS-OST | Hyperdimension Neptunia U: Action Unleashed SOUNDTRACK – VGMdb (http://vgmdb.net/album/52338)
The only active link I’ve found provided that format; as far as I know, AAC files generally provide better quality compared to MP3(s) encoded at the "same" bitrate.
Was curious how the music was in this game and dang, it’s a lot better than I expected. Thanks for sharing!
