The format has been slowly morphing back to its early days for the last 6 or 7 years, being as the last big "Rock" record on the format was Rope by the Foo Fighters, released back in 2011. Gone are the days of alt rock stations playing to an audience who listens to shock jocks, as well as panders to a crowd that thinks to non-loud music is for sissies. Some hard rock is good, but being loud does not always mean the artist has talent, or makes anything music worth while regardless. Not every grunge-flavored rock band could fit in Chris Cornell or Dave Grohls shoes, some not even close.
Could more female artists be given a boost, why certainly? Charly Bliss, one of the artists mentioned in the article, sounds a lot like the power-pop albums promoted on the format in the early through mid 90's. Think a cross between early Weezer and Matthew Sweet.
A format that embraces the best music overall: including power-pop, EDM, Shoegaze, Sythpop, Punk, Garage Rock and Hip-Hop shall win the hearts of listeners. By focusing on a few bands destined for arena-rock madness, such as Imagine Dragons, would be a disservice to the public. Case and point, could a format styled after college radio or adventurous Modern Rock stations of yesteryear get good ratings? Maybe, maybe not? On the other hand, any sane individual of a certain age feels a lot more nostalgic for DJ's like Steve Masters playing Mixshows on Live 105, then that alt station circa-2003 that had a fetish for playing that 3 Doors Down song that became a recruitment song for the US Army.
Then again, maybe the Lilith Fair era wasn't that bad? May be subjective but some of the music seems to have held up well, or at least wasn't that dreadful noise that came right after in the form of nu-metal. I mean, Alanis Morrisette and Sarah McLachlan had some good songs, even if some of the music didn't get your testosterone pumping. Blur, Mighty Mighty Boostones, Radiohead, Fiona Apple and various other artists got airplay on alternative radio between the end of grunge's dominance in 1996, and the back-wards ball-cap carnival barkers that dominated the format in 1999.
