Interesting, I never really considered very large tracks.
librespot doesn't load the whole song into RAM, but it downloads it into /tmp, which may be the same thing if that is mounted as a tmpfs.

As a temporary workaround, you can change this line from NamedTempFile::new() to NamedTempFile::new_in("/somewhere/not/in/ram").

Ideally, if a cache directory is specified we can just use $CACHE/temp automatically for that.

Thanks, I will try this. In fact, this track is an extreme. It my also happen for tracks having a length of six or seven minutes, depending on the free RAM left.

On second thought, my system is NAND flash based. So, using anything else than the RAM for caching is not a good idea. So, I need a bigger RAM?

Pretty much. A solution would be to change librespot to break up the files in blocks of say 500KB, and delete them automatically (if cache is disabled) once it has moved on to the next one. This is a large-ish change, so it's unlikely I'll be able to implement it anytime soon unfortunately.

I've modified librespot to disable the audio file-cache. See pull request #181.

The final PR for this was closed. See here.

This is different from plietar/librespot#204. The issue here is that librespot tries to download the entire file (whether or not cache is enabled), which may be impossible for long tracks and low memory devices.

Yep, I had to learn this the hard way: though I had the audio-cache disabled I still saw people with large files in TMPDIR. In my case I was able to work around this using the method mentioned by @plietar: have librespot write to some place outside in-memory storage. Setting TMPDIR=/path/to/folder librespot ... does the trick here.

given that all spotify songs are downloaded in chunks, is there an easy way to discard chunks once they have been played when the cache is disabled?
