Ringtones available in Mono, Poly and Real
The kings of rock/ pop U2 sang Beautiful day in 2002 in their album “All That You Can't Leave Behind” and it has a nice guitar hook in the middle with a great piano solo and can be downloaded as your personalized ringtone from most websites in all three formats- mono, poly and real.
 
Some of the lyrics are:-

The heart is a bloom//Shoots up through the stony ground//There's no room//No space to rent in this town//
   
You're out of luck//And the reason that you had to care//The traffic is stuck//And you're not moving anywhere//
   
You thought you'd found a friend//To take you out of this place//Someone you could lend a hand//In return for grace//
   
It's a beautiful day//Sky falls, you feel like//It's a beautiful day//Don't let it get away//

The music for Beautiful day is available in all the three formats but the lyrics are only available on realphonic format. U2 is a heavy rock band whose ringtones contain electronic sounds and its popularity for over 20 years is a testament of its longevity and excellent choice of songs.
