Default [Q] Anyone know any good ringtones?

Hey all,

Hope I'm posting this in the right area;

I was wondering if anyone knows of any decent ringtones that's not some stupid song, like "Happy" by Pharrell Williams or the crazy frog theme tune, for example.

And the default sound set that comes with Android leaves a lot to be desired.

Something simple but different would be great.

Got any ideas?

Cheers,
