I decided to make a thread of UTAU's who have commercial use allowed. This thread may get bigger with time, feel free to add onto it! (yes it can be your own UTAU ^^!)
Note: I will add some descriptions on the UTAU's, some of them are in the UTAU's page itself, some are in the comments, etc.
[★] = I have used the UTAU before
[❤] = I personally like the UTAU
