Some of the older releases were previously only available on iTunes or Loudr, but Loudr stopped selling them. Materia Collective is gradually putting as many as they can on Bandcamp, which requires getting new licenses. Bandcamp is a great platform, since 85-90% of sales go directly to the artists or labels, plus they offer a wide variety of music formats, including the lossless formats FLAC and ALAC.

You can stream all the albums on Materia Collective's Bandcamp site, and if you like them, please support the artists and buy through Bandcamp so they can keep making great game OST's and remixes!
