Escape the "special" character by using a \ so in your case you would
say: "only one brace here\[anything.mp3" which the regular expression engine
will translate to: "only one brace here[anything.mp3" instead of "only one
brace here<Open a caracter group>anything.mp3" which would mean you never
close the group and thus the regular expression is invalid and will throw an
error.
