If loops causing errors in bash script

I have a linux scripting project I'm making for school. I'm making an MP3 player but I have only just started making the interface and already ran into problems i can't seem to fix. The problem seems to be linked to the if statement, something that i keep having problems with even though my syntax is right. The code is in no way finished. mp3Player.sh is the name of my script.

This is the error message I get when starting the script, it just keep printing these three lines to the terminal until i force stop it:

./mp3Player.sh: line 44: [: too many arguments

./mp3Player.sh: line 47: [: too many arguments

./mp3Player.sh: line 51: [: too many arguments
