I have to agree with Doug. Radio stations have all sounded the same to me for decades now.

I don't think it's the fault of any specific corporate conglomerates, just the corporate profit mentality. I will admit, in some cases, that mentality doesn't appear until after a large company buys a smaller one, but in general, all the radio stations sounded the same to me for a long time anyway.

Every town has always had the same AOR and Country stations. The AOR stations always have the same playlists, they're K-Zeppelin and K-Credence all the time. I never understood why, but that hasn't changed since I was in high school.
