It's interesting that several of the songs that have been posted so far have their origins quite a few years ago. It looks as if Reba has decided to bring to the fore songs that meant something special to her, but which she hadn't had occasion to use before - and, in that sense, this album may be quite personal, and a "labour of love". Some of them take her closer to her roots, and may, perhaps, be something of a statement, not simply falling into line with current trends.
That certainly seems to be the case with the two Reba co-writes. As rcramer said, "No U in Oklahoma" is in traditional Western Swing style. Reba says that Donna McSpadden brought the idea to her years ago, though she's only now recording it. Both co-writers have Oklahoma connections. I think the McSpadden family, who seem to be long tine friends of Reba's, were related to Will Rogers, and have been prominent in Oklahoma politics. Although Ronnie Dunn is a Texan, his early career was based in Tulsa, where this song would fit so well)
"In His Mind" was co-written with Liz Hengber, who has been a big presence in Reba's career - her previous song hits for Reba include And Still, Forever Love, Its Your Call, & For My Broken Heart. Again, this draws on a tradition, in female torch singing, that Reba's been very successful with in the past.
There'll certainly be a lot of nostalgia here for her many fans - and respect from her peers - but it remains to be seen how far the radio programmers, and the tastes they concentrate on meeting, will react. (That, though, may not be her primary concern!)
