Using MimeType text/xml is not really usefull. Suggest specific application mime types. #2134
Description
Mime type text/xml is far too generic to allow making file association with hydrogen.
I'd suggest defining clear mime types, such as
application/hydrogen-music-h2playlistapplication/hydrogen-music-h2drumkitapplication/hydrogen-music-h2songapplication/hydrogen-music-h2themeapplication/hydrogen-music-h2pattern
Since I found no installation scripts for the appimage, I created my own script to create better mime types and application desktop entries.
After running this script any h2song will be opened by hydrogen on double-click in file managers.
Please feel free to use this as template for your own installation script:
#!/bin/bash

# get the icons from github

ICONS="icon16.png icon24.png icon32.png icon48.png icon64.png"
for icon in $ICONS
do
if [ ! -f "$icon" ]
then
wget "https://raw.githubusercontent.com/hydrogen-music/hydrogen/refs/heads/master/data/img/gray/$icon"
fi
done
#----------------------------------
# install icons

for png in icon*.png

echo "png='${png}'"
