why not buy the album and then use it locally on your device? vlc runs pretty much everything and you could fit thousands of songs while offline (could even remove the gsm/wifi/bluetooth from a phone running some FOSS os and turn it into your offline media device). or just get a cd player for $1 at a thrift store, offline, private, full access
thrift stores sell albums for $1 and there are a few sites that sell new music to be downloaded for cheap
