The low-$p_T$ part of the pion spectrum measured by the ALICE collaboration has turned out to be very difficult to reproduce using conventional fluid dynamical approaches. In this talk I discuss how the finite width of $\rho$ mesons affects the yield of $\rho$s and the distribution of pions originating from $\rho$ decays, and how inclusion of the finite width in the description of resonances may help to explain the low-$p_T$ pion data.
