Organizing sound files comes with a number of challenges that aren't present when organizing photos or videos.
These difficulties all boil down to the lack of a meaningful visual representation of the sound: you can look at a thumbnail grid of 100 photos and quickly take in what is in the photos - but a thumbnail grid of 100 sound files more often than not look like this:

What we'd like to achieve is a system where we can quickly tag sound files with searchable textual descriptions - preferably automatically - and also some way to be able to look at the file (as displayed in most media asset managers) and get some idea of what is in there.
I ended up with the following solution: take a photo of the recording site, and set it as the album cover of the resulting FLAC file. Using metaflac this was really easy. Now my thumbnails look like this:
