Agreed, this is the ringtone that I have run on every iphone I have had(2g, 3g, 4) After years of using it, it still garners comments from strangers about how "creepy" and "cool" it is.(If I have the phone set to ring, which is rare, it is on silent about 95% of the time).
I have never really been a fan of musical ringtones, I find them irritating most of the time. I probably feel this way due to the vast majority of "gangsta" types at my school who ALWAYS seem to forget to silence their phones during class, resulting in some distractingly loud, badly distorted clip of some god-awful hip-hop "music."
Off topic, modern hip-hop has gotten unbelievably bad as a whole. The only music of that type that I will listen to is all from the early-mid 90's. Today's autotoned garbage is just the total suck.
Lately I've gotten tired of music ringtones. I'm using the Two-Volt (2x) from Ambientrings.com at the moment. When I feel like changing again I'll go back to my video game clips and miscellaneous sounds.
A guy who has the oddest ability of calling me after we (he's the boss at one of my jobs) mention him got me to make Monty Python's Spanish inquistion monologue into a ringtone.
My brother's is the laugh at the end of Thriller.
One friend used to have a woman screaming format ringtone. Think it might currently be Avenue Q's "I'm not wearing any underware" (hendoesn't around the house. Long story.) Also he was without a job when I set it.
Another friend is set to "Tank" from Cowboy Bebop (Opening Theme).
