What instrument please? Because if it's the guitar, I don't believe you. You simply cannot play that song until you're able to play relatively fast for a beginner.
Well, the "easiest" song is hard, because there are a lot of practice songs. My first piano book had an excercise in tempo called "The Piano Tuner" where you played C all over, varying between quarters, eighths and a few halfs.
Easiest licensed song? I think every guitarist learns Smoke on The Water* or Seven Nation Army, every flautist/piccolo-ist(?) learns My Heart Will Go On, etc.
*If you're not playing the main riff with the 3rd and 4th strings, you're not a guitarist.
EDIT! Oh! Oh! For the guitar! Horse with No Name and I Used To Love Her
