I’m probably surely showing my age, as many of my suggestions would be from the 70’s, give or take.
Additionally, I would tend to use the same stuff for a walk/run mix as I would a good road mix.
If you’re into Southern Fried Rock, as Oakminster suggests, I’d go for more Skynard, such as: Call Me the Breeze, Gimme Three Steps, I Know a Little, and Honkey Tonk Night Time Man. Then, I’d have to add my fav, Marshall Tucker: 24 Hours at a Time, This Ole Cowboy, Fire on the Mountain, I’ll Be Loving You, Change is Gonna Come, Running Like the Wind, Last of the Singing Cowboys, Cattle Drive, and…I should stop that now. I could go on and on. Then, perhaps some Charlie Daniels, Outlaws, Allman Bros, CCR, Little Feat, IF…you’re into that kinda stuff.
I have a older cassette that I loved to walk to - Contemporary blues: Delbert McClinton, Bonnie Raitt, Robert Cray, SRV, Gary Moore, and a bunch of songs off The Alligator 20th Anniversary Collection.
I’ve got a few others w/ good Motown/Phil soul mix, and an alternative (dated) of w/ Third Eye Blind, Sugar Ray, Barenaked Ladies, The Cure, Sara McLaughlin, Paula Cole, Sheryl Crow.
Then, there’s Tom Petty…I can’t think of a better road song than Running Down a Dream, and he’s got SO much more great stuff.
Hey, that brings up Traveling Wilburys…hell, if you don’t have it, just buy Vol 1.
I hesitate to go into too much detail here, since some of the other musical threads I’ve seen contain artists and songs I have never heard of, so I feel I may be in a definite time warp…Beatles anyone???
