Escape detected songs before using as regex

Strange song info can turn out to be a malformed (malicious) regex.

Example of that 💩?

Yeah so the song that crashed everything had an imcomplete title in the ICYINFO coming down from the server. I don't have the exact string now, but it was something along the lines of

Rad Artist - Rad Song (Remix feat. Other Ar

If you try to compile that as a regex, you'll throw an sre_constants.error: unbalanced parenthesis.

I say (malicious) because it's not sanitized whatsoever. If there's anyway to get the regex compiler to freak out by sending a specially designed string down the pipe then it will explode.
