Was there? I have been google'ing that problem for ages..
Just one more thing. I have to make a menu system where the user chooses
what functionality they want. Because you cannot change a value once it
is set I have used recursion so that when something changes it then
calls the menu back up. I feel this is way to memory consuming. Is there
main catalogue playlist:
x = choose option
function1 1 = main (functionName value) playlist
function2 2 = main catalogue (functionName value)
