Ya, i hear little vibrato in Spencer's voice, and i don't hear it at the end of any lines. And for god sakes, everyone stop referring to the singing style as "emo".
Firstly, i don't find Spencer to have to whiny high school scene band sound in his voice. AT ALL. Neither does he sound like an emo screamer to me. He has a bright timbre to his voice, and y'all wanna crucify him for it.
The first thing that comes to mind when I hear him are the emo/screamo-type vocalists I've heard. Sorry if that bothers you, but from the overall sound and style that's where I end up with him - not nearly as annoying, but there's definitely something to the comparison.
