regex halp

Hey /prog/,
I'm trying to make a regex to grab file paths out of the txt file itunes gives as a playlist but I keep getting crap mixed in. What am I doing wrong?

(\s+)C:\\Files\\Music(.*\.\w{3})\n
Translation: More than one whitespace, file path, any number of non-newlines, a period, any 3 alphabet characters (the file extension), and a newline.

No matches with the carriage return.
what operating system uses "\" as a path separator and has DOS "C:" faggotry and doesn't use "\r\n" for the ends of lines?
What's the '?' for? Isn't it for +/- a single character?
*? = non-greedy *

\s+C:\\Files\\Music((.+)\.(\w{3}))\n
some_file.flac
OH SHI-
