Update: The developers contacted me about my review. They said they were incorporating more old stuff. They also said they have something for older stuff Saturdays for it. I might try it in the future.
Original review: This app caught my attention because I love Christian hard rock/metal. At first use, I thought it was okay—as it went on, however, I noticed that they would play the same songs a few hours later after they had played it a few hours previously. I then noticed that this was the regular way they did this. I kept the app after this realization, seeing if they would mix it up—they didn't.
My main problem with this app is that I think it's too limited. I think it needs WAY more older stuff, (E.G., older Disciple, Skillet, etc.) They did play some older things, but they were few and far between. I understand that you need to play new stuff, but not everyone likes the new stuff (raises hand.) I think they should mix it up a few days a week with older stuff. (When I say older stuff, I mean Disciple's Back Again, By God, etc., and Skillet's Collide, etc.)
Overall, I give this app three stars. Too limited.
