* /music is not a physical directory
What is /music? Is this URL proxied? Is the content for this URL generated by a script? Something else?
* In one sentence, the problem is to redirect specific urls (a) to a
page only if that specific url (a) has a 503 error.
The easiest way: 503 errors are not normal. Find what is causing the error and fix it. Alternatively, if the 503 error is being returned deliberately as a status by a script, modify the script so that the script does a 302 redirect instead (for example, to http://google.com/music)
Another way: set up an ErrorDocument on your server (not on google.com) to handle all 503 errors. Have this ErrorDocument be a CGI script or other active content. The script should examine the REDIRECT_* environment variables set up by Apache HTTP Server to determine which URL the user was requesting, and, if the user was requesting /music, the script should generate a 302 response to redirect the user to http://google.com/music If the user was not requesting /music, then the script should do whatever you want done in the case of a 503 error (display an error message for the user, etc.). For details, see https://httpd.apache.org/docs/2.2/custom-error.html
A harder way: Write an Apache HTTP Server module to do exactly what you want. An alternative to writing a module in C would be to use mod_perl: https://perl.apache.org/docs/2.0/user/handlers/http.html
