# I searched for this capability and I found a bunch of versions that do it with really complex
# full scripts, which also don't really add any more capabilities to what I offer here with a simple oneliner

# I don't know if you could consider this a bug but if you have more than one album with the same name
# all of them will be added to the queue


# This works
#mpc findadd album "$(mpc list album | shuf -n 1)"

# Made this one because I didn't remember the name of the xargs command so I had to come up with
# a different way to accomplish this task. When I remembered the name xargs I rewrote it


# This also works plus it gets rid of double quotes, so you can use more easily inside other commands
# AND you can do more albums at the same time by changing the number after "shuf -n"
# the -d$'\n' option in xargs sets the delimeter to newline and lets us have quotes inside the argument we are passing to xarg
#mpc list album | shuf -n 1 | xargs -d$'\n' -I % mpc findadd album %

# The rest of the comands are what I have for my specific use case, but the important part is whats above
mpc clear && mpc random off && mpc list album | shuf -n $num | xargs -d$'\n' -I % mpc findadd album % && mpc play
