Like when I sing right, I will sing it in tune but than i wouldn't feel it, like it would sound awkward like the flow, it wouldnt go with the beat but when I write it, and say it, it sounds perfect, I dont know why but I keep extending like holding the last note :S
Like when I sing it would be like:
She wanna beee a drammmmaaaaa queen
when I coming into (pause, dont want that) the sceneeeeee
ill tell you a trick that works
try and get scared before you sing or scream a bit before (even if your a guy) and that way it makes your voice clear. Also try having some honey.
if you want you can join a singing lesson..
