Delete all tracks from MTP device

My MTP MP3 player does not allow to delete all albums with one command (yes I really wanted to delete all tracks ! )

Bash to the rescue :
mtp-tracks | grep 'Track ID' | awk '{print $3}' | xargs mtp-delfile -n

Of course you must install the mtp-tools, on Ubuntu :
sudo apt-get install mtp-tools
