Who knows: Maybe this "change" supposedly coming about may be because "soft-rock" stations, whose bread-and-butter has been Billboard's adult-contemporary chart, are starting to get second thoughts about such a format if songs with names like "F-in' Perfect" are getting into the top 10 on that chart. There was that "Before He Cheats" fiasco a few years ago. Lately we've had to put up with some song with terrible rhymes ("Radio, stereo, I can't stand Denny Terio").
The solution hits one's brain right away: "Why don't Billboard have a separate soft-rock chart, like they have a separate 'pop' chart?" One look at the current "pop songs" chart will show the junk that's creeping into it. This stuff is now creeping into the adult-contemporary chart. Pretty soon, it would creep into a soft-rock chart as well. I hope that at some point soft-rock (or "easy hits" or whatever) stations will dig as much as they can for new, quality songs, with the kind of sound they're going for, without feeling like they have to go along with a chart.
Yes, this will probably mean playing the next thing in the mail from an independent-label artist, that fits the format. And/or an on-the-shelf album track that goes along with the format pretty good. Maybe a bruised ego or a cramped style, but probably the only way to save soft-rock.
