Introducing pleezer: a Deezer Connect player

[Tim Curtis]

Where is the default on-disk location for tracks?

Default system temporary directory, so /tmp.

This is also the case for librespot, although I remember I made it a command-line option to choose another temporary directory. RAM storage I did not implement in librespot.

The /tmp dir at least on PiOS is mounted by systemd as type tmpfs which AFAIK is a RAM based file system.
