There is something that is supposed to be inherently cutting-edge about the Alternative format. You should be going deeper with your music catalog than other stations. In general, fans of the format listen longer and tend to be a lot more dedicated and loyal.
Radio 104.5 isn't an Alternative station. They're Classic Rock for the under 40 crowd, with liberal doses of slick bubblegum pop (i.e. Blink 182, Fall Out Boy, Paramore) to lure in the younger audience. They mostly ignore the '80s, with the exception of the safest titles from the biggest arena rock acts of the era (i.e. Police, U2). I see a heck of a lot of irrelevant lightweights on their playlist, like Fuel, Finger Eleven, and Puddle Of Mudd. They mix in plenty of non-Alternative acts like Stones wannabes The Black Crowes, latter-day Bon Jovi sound-alike Goo Goo Dolls, and dreadful soft-rock dullards The Fray. And in their eyes, there isn't a single song that has become worn out. You name the most played rock song of the last 20 years, and they're playing it as much today as many stations played it 10 years ago - perhaps even more than that. But perhaps most frustrating about the station is what they won't play. I have never heard them play anything from R.E.M.'s first four albums, anything from Depeche Mode other than "People Are People" or the Violator album, anything from Jane's Addiction other than "Jane Says" and "Been Caught Stealing", anything from Blind Melon other than "No Rain", anything from James other than "Laid" ... and the list can go on and on.
Perhaps most baffling about this station is that the music is supposed to be the only hook. Bland station IDs and advertising, repeatedly boasting about how little talk they have (isn't that branding we're more accustomed to from Adult Contemporary stations?), and often little to no DJ presence at the station ... I know for a fact that Cheap Channel runs a few shifts with "Otto Mation" manning the boards.
Radio 104.5 is doing well now, but it won't last. The music will become very stale, and the station will have to evolve in some way. My advice would be to have personalities at the station 24/7 and let them talk (that doesn't mean they need to have a "dude talk" morning show), find a way to become more listener-interactive (how about a Retro Lunch and All-Request Saturday Nights?), and for Pete's sake - open up the playlist a little bit! Why do they think that alternative rock fans want to hear the same songs day in and day out? 20-25 Currents and continuing to work over the early '90s Seattle sound with little else to offer will bore the audience, and it will happen soon. But it's Clone Channel at the helm, so I won't hold my breath for any positive change. They don't have any passion for the format, and they put people in charge that would be more at home programming Top 40 or Hot AC.
