I'm probably as big an Eagles fan as I am of Linda Ronstadt, given that they are each linked in music history (recall that before being called the Eagles, they were Linda's backing band during a tour she did in 1971).
I haven't heard their new single yet, but we have quite a few Classic Rock outlets here in Los Angeles that will likely be playing it in the coming weeks. I kind of doubt Top 40 radio will touch it; they're too busy playing mindless drivel from the Britney Spearses of the pop world to bother with these guys. They will also be the ones to christen the new Nokia Theatre in Downtown Los Angeles on October 18th, with their supporting act being the Bushwhackers...er, the Dixie Chicks

.
I know that this may tick a few people off here, but one thing that has consistently bugged me ever since their Hell Freezes Over tour of 1995 is how the country music industry is claiming that the Eagles' 1970s records would be considered "country" today. I have a very difficult time buying that notion for a lot of reasons, but I'll give just two for openers.
One is that, if they're really "country" at all, it is a style of country music endemic to California, rooted in the 1960s folk music revival and spiked with elements of R&B, which, as Linda herself has said, is a "hybrid, very specialized, and it doesn't have
anything to do with Nashville."
Secondly, the subject matter of their songs often focuses on the dangers of the fame, fortune, and fast-living of urban life, specifically the L.A. of the 1970s that they knew more than a little bit about. Would the musical and lyrical content of "Hotel California" or "Life In The Fast Lane" ("We've been up and down this highway/haven't seen a godd***ed thing") work uncut n a format that includes "She Thinks My Tractor's Sexy" and "Whiskey Girl"? I don't think so.
We have to look at the Eagles, however influential they may be on today's country music, as being radically different in terms of musical style and lyrical content from, say, Rascal Flatts or Lonestar. They are a much darker and more brooding band than I think they're given credit for.
