Which Songs Make Good Ringtones?

So, was wondering which songs make good ringtones?

I thought about C- BooL – Wonderland. What else?
I have "Green Onions" by Booker T. & The M.G.'s on my cell. It never fails to elicit smiles when it plays in public. Wicked guitar playing by Steve Cropper.
"Watermelon Man" - Herbie Hancock!
Crazy Train .. The Ozman!

Fly From the Inside ... Shinedown.

Both really loud and just the right pitch and notes to stand out.
Rihanna’s S&M(especially, the, "sticks and stones" refrain)
Giant Steps by John Coltrane

The Maryland Pacesetters Steelband Orchestra has a cover of Marvin Gaye’s “Sexual Healing” that I use on my phone.  Distinctive, easy to hear in a crowd, and usually elicits a smile once people figure out what they are listening to.


Any suggestions on a good free app or website for making ringtones from flac & aiff files? The one I used to use shutdown. Cheers,
"I Hear You Knocking" by Dave Edmunds. It’s both a great song and apropos ;-) .
Rock Candy by Montrose. The opening guitar grabs you.
