You know what's odd? I've gone over sheet music with people and had them say the same thing, but they often point out things I already heard. It happens most often for songs I'm really familiar with and have played tons and tons. IDK what it means; I think my brain is wired funny.

Piano icons: I found this (http://mollsex.livejournal.com/14234.html) on a quick look. There's probably music icon communities on LJ that might have more.

Also, happy birthday. =)
