Nightcrawler,

It's hard to help you with the actual regex, since your requirements
aren't completely clear to me. However, what often helps me with
regexes, is to split them across a few lines of code to improve
readability (use Stringbuilder or +=, according to your need for
speed).

Each line would have a part of the string you're trying to match. It
seems to me you need:

1. start of the string (?)
2. "title", exactly that string
3. 0...many whitespace characters
4. either a "-" or a "(" or a "[" character
5. "remix", exactly that string
6. optionally, either a ")" or a "]"
7. end of the string (?)

Perhaps the above will help you refine requirements, and then write
the regex yourself. I really suggest splitting the regex in your code
into separated parts as well, this greatly helps folks (including
yourself) read back a regular expression.

Regards,
Jeroen

my advice to you is to find a regex tester and work it out yourself, an
example of a regex tester can be found below...
