Anyone got access to any/all of the music CD's from the excellent 2014 anime series 'Jinsei' in FLAC/lossless?

It seems they were only released as enclosures with the series on blu-ray - I can't find them anywhere.

Vol 1 https://vgmdb.net/album/48076

Vol 2 https://vgmdb.net/album/48155

Vol 3 https://vgmdb.net/album/48766

Vol 4 https://vgmdb.net/album/48767

Vol 5 https://vgmdb.net/album/50453

Vol 6 https://vgmdb.net/album/50534

Vol 7 https://vgmdb.net/album/50535

Vols. 6 & 7 are the closest thing to a 'soundtrack' album, the others being effectively 'singles' with just a couple of tracks each, so if I had to choose, I would rather have vols. 6 & 7.

I would be eternally grateful if anyone has, or can find, these! :-)
