Ask HN: Buy lossless music with Google Play credit?

Ill complicate this to start by saying the album im after is a new release from a somewhat obscure japanese band which may make things a shade more difficult.

but im looking for any app other than play music which i can use to buy music on, the album is on play music but im loathe to pay 10 quid for an MP3 album even if i did earn the credit for nothing from surveys

i have so far tried ototoy and yamaha mymusic but sadly neither accept in app purchases to buy albums. if not i guess ill just have to pony up and buy it in cash but id like to use this credit for something
