[SOLVED] Wrong main artist

Hi!
I uploaded a song that's a duet with two singers, main voice and 2nd voice.
I put the song under the name of one artist, but I was wrong, he was the 2nd voice, the main voice was the other. I changed it to attribute the song to the right guy, and put the other one in "featured". So far so good, now it appears under the right singer's songs.
HOWEVER the url still mentions the wrong singer.
Should I delete the song and re-do the whole thing, so that the URL has the right path?

If you're curious, this is the song:

Singer A: Spyros Vlassis
Singer B (2nd voice): Vassos Seitanidis.
But as you can see, the URL says "vassos-seitanidis".
