Is there a stack overflow site which allows a user to enter the music they hear in their head as some representation (a musical staff, voice/sound recording, or even mario music style interface) and then people tell you what the name of that music is (even if the representation corresponds to no music whatsoever and they just call you a dumbass)?

Example:
 I hear dun dun dun duuuuuun. G-G-G-Eb. This is Beethoven's 5th symphony wandering around in my head but I don't know the name. Maybe i'm hearing a transpose of it because I haven't heard it for a while. I go to this site and somehow input this so others can play it back and tell me it's Beethoven's 5th. Is there any interest in this kind of technology?
