#5 & #2: These are both cool, but #2 is a little too obvious. I want to keep the marcato music in the logo. The note hanging down is a cool effect, but it makes me think of a J (a guy I know has a site just like mine called "jw3" and it reminds me of that).
#5 is cool--I like the two accents, but the note looks like a cross when it goes through the T. I don't want any sort of religious confusion! :)
Thanks again! Keep up the good work!
Also--I thought the staff coming out of the "m" is interesting--I haven't decided if I like it for what I'm doing, just it looks cool.
