As predicted, five-year-old Rock 100.5 has now incorporated the 98.9/The Bone playlist into its existing rock mix, sounding younger and harder.

This pivot to skew younger is a way to capture disaffected Project 9-6-1 fans who found the 98.9/The Bone signal lacking.

Musically, this means 1980s hard rock, 1990s grunge and 2000's-era mope rock will blend with current active rock.  The Regular Guys remain in place.

The first 10 songs:

9:59 a.m. Third Day Grace "Chalks' Outline"

10:02 a.m. Metallica "Enter Sandman"

10:06 a.m. Theory of a Deadman "Bad Girlfriend"

10:11 a.m.  AC/DC "Thunderstruck"

10:15 a.m. Shinedown "Bully"

10:20 a.m. Pearl Jam "Alive"

10:24 a.m. Black Crowes "Hard to Handle"

10:29 a.m. Ozzy Osborne "Shot in the Dark"

10:32 a.m. Foo Fighters "The Pretender"

10:36 a.m. Red Hot Chilli Peppers "Give it Away"

Mid-day jock Lyndsey Marie Tweeted that "I'm excited for louder rock."

My guess this means mellower acts such as Collective Soul, Pink Floyd and Neil Young might take a backseat to Avenged Sevenfold, Chevelle and Five Finger Death Punch. Older acts with edge such as AC/DC and Black Crowes were played during the first 30 minutes of the revamp.

This move can't hurt 97.1/The River, which has already seen its ratings bolstered by the departure of 92.9/Dave FM. The River will now be the exclusive classic rock station in town.

Still missing: a genuine adult alternative station in town.

Will Cumulus fill that gap at 98.9? Who knows? For now, the station is simulcasting Rock 1005. Rumors range from Christian to country to alternative.

Rock options have shrunken from five stations to just two on the FM dial right now in a matter of a few months last year. Project 9-6-1, the active rock home, became top 40 in August. In October, Dave becamse sports talk. And the Bone at 98.9, which debuted late summer, lasted all of five months.

Axel Lowe, a former 99X afternoon jock, returns to the afternoons on Rock 100.5 after a brief stint on the Bone. (He actually jocked at Rock 100.5 before, too.) He will be heard from 3 to 7 p.m. He replaces former 99Xer Matt Jones, who moves to promotions. (Jones, if you may recall, was the long-time Sunday Organic X guy.)

Rock 100.5 has shifted its music around multiple times over the years, sometimes going more classic rock, sometimes harder, sometimes softer, sometimes no currents, and most recently, a few recent songs.
