Among other genres, I'd start with a channel dedicated entirely to classic country music TV shows.
Y'know, those programs put out by superstars of the era and they had regular performers along with a guest each week. Shows such as "The Porter Wagoner Show," "The Ernest Tubb Show," "Buck Owens' Ranch," "The Wilburn Brothers," "Marty Robbins Spotlight" and a few others, all from the 1960s through late 1970s. (Porter ran as late as 1981 in some markets.)
Another favorite I'd put on such a channel is "Barbara Mandrell and the Mandrell Sisters" show from 1980-1982. Remember a lot of Saturday nights growing up and watching this show. One of the last successful variety programs.
The schedule would be rounded out with programs like "Hee-Haw," "Pop! Goes the Country" (hosted by radio personality Ralph Emery) and "That Nashville Music" (which had a bunch of cloggers as one of the regular acts). Those shows ran mainly in the 1970s and 1980s, although "Hee-Haw" ran as late as 1992. Also a rarity from the early 1990s that tried to capture country music's growth of the time: "Hot Country Nights"; this ran briefly from 1991-1992, so this might be a once-a-weekend show since there are only 18 episodes in the entire series.
