I am far from an expert, but I have used MusicMaster for many years (since 1991) on several top rated stations in CHR & AC formats and now with Country on Y100 the #1 station in both the Green Bay and Appleton-Oshkosh markets. The biggest things I have learned about MusicMaster are: Check & double check the info you input. Schedule currents first then check the log and lay in the gold. Make sure the math makes sense when you design categories. Don't forget about the "song list editor" this works great for special weekends and countdowns.
