thats a cool idea...though it wouldnt have worked for me in the same way it will for you.... I didnt have co consciousness with most of my alters and those I did have co consciousness with it wasnt a situation where I would know them very well, it was more like something would cause me to dissociate (feel numb, spaced out, disconnected...) and then the alter would be taking care of that which caused me to dissociate.

for example heres what would have happened for ....me.... if I had tried to give my alters a song that represented who and what they were....

if there was a major storm going on that would trigger my dissociation responses, which would cause Rainy to take control. then she would deal with the storm by making sure we got home our of the storm, into our jammies and wrapped in a blanket.

the song that would represent this would be a song where a storm was represented (lots of rain, thunder and lightening sound affects) which of course would then trigger me into dissociating which would result in the alter taking control shutting off the music, get us into jammies and wrapped into a blanket.

on the reverse side of this my treatment provider and I through the charting process learned that Rainy and my other alters already had their own songs, Rainys was "this little heart of mine let it shine let it shine let it shine" (she would add to it the words and chase away the rain) and also the song "its raining its pouring the old dog (substitution for man) is snoring". Thelma's favorite song was "Rocky top", some of my alters loved new kids on the block, cher, debbie gibson and b*witched.

suggestion maybe have your alters help you pick the songs too, that way you wont have to do the youtube binge thing if you dont want to and who knows they might already have their own songs that you can use to represent them.
