How bright is the extragalactic radio sky - in other words the Cosmic Radio Background (or CRB)? This question can be answered in 2 ways: by making absolute measurements at different frequencies,(which is hard); or by adding up the contribution from individual sources (which is easy, but only gives lower limits). Here we use a compilation of radio counts to estimate the contribution of detected sources to the CRB in several different frequency bands. We apply a Monte Carlo Markov Chain technique to estimate the brightness values and uncertainties, paying attention to various sources of systematic error. We compare our results to absolute measurements from the ARCADE-2 experiment. If these measurements are correct and come from sources, then there must be an additional population of very faint radio galaxies, below where current data are probing. More specifically, the Euclidean-normalized counts at 1.4 GHz have to have an additional bump below about 10 micro-Jansky.
