that's a little insensitive isn't it? i know i'm new here, but i'm not sure that is neccessary. if you suck then say you suck, don't pull someone else down with you.
i'm not an amputee, but i still don't use my arms and legs much when i record vocals. i would assume my voice would suck just as much with or without arms and legs.
i don't sing like an ampute, i sing like a manate.
