Something I love about Lake Charles (and SWLA) is the local public radio station, KRVS. Radio Acadie has great programming, all the time. (No, this post is not brought to you by their underwriters, or anything like that.)
At home, in Memphis, I started listening to MPB. That's right, Mississippi Public Radio has better programming than the whole grand *cough* city of Memphis. I'd love to listen to WKNO Memphis, but other than the weekday news and some of the weekend broadcasting, it primarily plays classical music. Not that there's anything wrong with classical: I enjoy a bit of Mozart and Bach here and there, but unless it's Tchaikovsky's 1812 Overture (that's pt. 1, pt. 2 here), classical is not my preferred driving music. And somehow even MPB's classical radio is better.
Anyway, KRVS has awesome music, almost all of the time. And when it's not awesome music, it's sweet talk radio. Radio Acadie plays plenty of Cajun and Zydeco, and there's even some programming in French. They also broadcast tons of different folk, bluegrass, and blues music, David Dye's World Café, a baller Monday night opera show, and quite a bit of jazz. On the talk side, there's the usual Morning Edition, All Things Considered, and Fresh Air, as well as This American Life, BBC (at a reasonable hour!), and all sorts of Louisiana Arts programs, including From the Poet's Bookshelf.
If you're in LA, here's a schedule. If you're not, hopefully your state likes public radio more than west TN.
Louisiana may lag on all sorts of state ranking lists; however, the Sportsman's Paradise has managed to provide one of my favorite public services.
Here's a song (kind of) about the radio. Sure, Courtney Love might be a horrible human being, but love her or hate her, this song is pretty awesome.
