Dear Jenny, Blake, Pierre and Jason,

You know, I used to love you guys. In high school, between cutting classes and cutting myself, Rilo Kiley was my go-to band, the first listed on my MySpace page. Your album covers would inspire me to doodle similiar works while pretending to take notes in history class. Naturally, I grew a bit skeptical around 2005 when you became the idols of every angst-ridden 13-year-old girl in suburban America, but as a whole, I once considered myself a full-fledged Rilo Kiley fan.

Now, more than three years later, I’ve just heard your new album “Under the Blacklight,” and I have some sad news. In the words of your song “Breakin’ Up,” “There’s trouble between you and I.” In fact, I’ll be blunt – it’s over.

To be fair, I should admit that, given your recent decline in coolness, I never really listened to “Under the Blacklight” with the good will any album deserves.

Plus, whatever dubiousness I lacked was soon handed to me by your new record’s first track, “Silver Lining,” which reeks so thoroughly of commercialism that I felt an impulse to plug my nose.

After that, you offered “Close Call,” an equally vapid and overly polished effort, followed by “The Moneymaker,” a song laden with clues about the nature of your entire new release.

Correct me if I’m wrong, but I suspect “Under the Blacklight” of being a sell-out of the worst sort: an album that aims for cash-cow, pop accessibility and fails to produce much excitement.

Seriously, guys, I feel betrayed. Since when did you have any interest in making songs that sound like “American Idol” singles? Well, not every track sounds like that, but on the ones that don’t, it’s like you’re trying too hard to be cool.

Like “15,” for example – I mean, I guess it’s possible to craft a quality song about sex with a 15-year-old girl, but there certainly doesn’t seem to be any meaning in this ridiculous track.

And then there’s that terrible moment on “Dejalo” when Jenny sings “I’ve got some beer if you want to get wasted.” The thing is, when I hear that, I really crave that beer.

At least getting “wasted” would work as an escape from the grave disappointment of watching a band I once loved bending over to take it from “the Man.”

Oh, “the Man” and his capitalist demands. This time “the Man” is Warner Brothers, the big label producing this piece of trash. How much was the check they wrote you? Does it pay for your fabulous Los Angeles lifestyle?

With that, I’ll just stop for I fear I’m being elitist. “Under the Blacklight” is all in good fun, right?

For now, I’m choosing to believe that you guys know you put out trash, and just wanted the money. So I’ll give you one more chance.

But next time, I need you to return to your old-school style, when your catchy melodies and bouncy instrumentations were coupled with meaning and high emotion.

This is one of the worst records I’ve heard all year.
