Code review comment for lp:~ahayzen/music-app/add-url-dispatcher-album

After investigations I found that the url stored in the database is neither encoded nor decoded, it is somewhat in between.

If you have a track with the file path ending
~!@#$%^&*(){}[]:,;?+\'"\\ .mp3
It is stored in the database as
~!@%23$%25%5E&*()%7B%7D%5B%5D:,%3B%3F+%5C'%22%5C%5C .mp3
It appears from the url-dispatcher as
~!@%23$%25%5E&*()%7B%7D[]:,;%3F+%5C'%22%5C%5C%20.mp3

Therefore ; [ ] need to be switched to %3B %5B %5D and a %20 needs to be switched to a space.

Note that a / and = cannot be used in the filename as a / is used to declare a folder and a = breaks the command line arguments.
