I study the azimuthal asymmetry of the unpolarized Drell-Yan in the framework of the T-odd functions. I find, on the basis of quite general arguments, that for vertical bar q perpendicular vertical bar << Q such an asymmetry decreases as Q-2, where q perpendicular and Q are respectively the transverse momentum and the center-of-mass energy of the muon pair. Data support this conclusion.
