Ok, i gave her an 8 because she is sort the standard good singer voice i think when somebody tells me someone can sing. at least with black woman.
If you have an auntie and you tell me she can sing, i imagine she will sound like this. If she doesn't i'm either disappointed or asking why she don't have an agent.
The type you find killing it in your church choir. but not something i expect to make her famous unless she has a full package to go along with it, like looks, charisma, etc. There might be other people i give an 8 that can't sing as well as her for that reason.
