truthsayer... I wouldn't be talking. I haven't heard Jack's Mannequin so I won't judge the song.
You said you work for Cumulus right? All their CHRs are playing "Shattered" by OAR, including yours, which just cracked Top 50. My MMR search shows the majority of the stations on the CHR panel playing it are owned by that company. Companywide, they never played Metro Station. 60% gold/recurrent
It looks more like you have a personal vendetta against his station than anything else. It isn't a good idea to move slowly on music regardless of what each market needs independently, which is what Jan does. I understand the ramifications of being too early on a song, but when songs are working for an area and there is high demand, then it seems right to play them. Sitting on burnt songs and being reluctant to forge ahead makes you sound stale especially in this format.
