A generic model for the mesoscopic dynamics of “soft glassy matter” is introduced; with interactions represented by a mean-field noise temperature x . We find power-law fluid behavior either with ( x < 1) or without (1 < x < 2) a yield stress. For 1 < x < 2; both storage and loss modulus vary with frequency as ω x -1 ; becoming flat near a glass transition ( x  =  1). Values of x ≈1 may result from marginal dynamics as seen in some spin glass models.
