We get the point today that you are against this new station. I looked at the River's top 100 and only spotted a few songs so far played on 100.5 Based on what I have heard today and the River's Top 100 I would be surprised if more than 15 - 20% was a cross-over with the River.
I am not against the station or the music. I compared the Rock 100.5 playlist from various hours to the playlists of 97.1 The River, Project, and 99X using yes.com
At 3 PM...
Dire Straits - Sultans of Swing - played on 97.1
Van Halen - Top of the World - played on 97.1 (occasionally)
Alice in Chains - Man In The Box - played on Project and 99X
The Rolling Stones - Can't You Hear Me Knocking - played on 97.1
.38 Special - Caught Up In You - Played on 97.1
Aerosmith - Back in the Saddle - Played on 97.1
Nicelback - Rockstar - played on Project and 99X
Bad Company - Ready for Love - played on 97.1
Ted Nugent - Free For All - not played on any other station
Collective Soul - December - played on 99X and on Project (occasionally)
ZZTop - Just Got Paid - played on 97.1
Out of 11 songs that hour, I can easily find 6 of them on the 97.1 playlist. I also tried this with other hours and found similar results. Also, many songs that 100.5 played were found in the top 100 most played songs on 97.1 The River. So, it's not as if Cumulus brought a unique rock format such as deep album cuts or the Boneyard channel on XM. This station is mainly just 97.1 The River with a few modern rock tracks and the occasional deep cut thrown in.
