I'm not totally sure how I feel about it. I don't mind the singing part, because it is nice to hear something positive in a world where we're constantly bombarded with negative messages. But at the same time, I feel that's it's a little like commercials, evangelism, etc. I personally don't have TV and when I watch it, I can't stand the commercials because someone is always trying to get me to buy this or that that I don't need or want, and I have no choice but to put up with it. Except I change the channel, mute it, or leave the room. Same goes with radio commericals: whatever it is, I don't want it. I want to be able to think with my own brain and not have something shoved down my throat all the time just because it's allowed in society.
At the same time, I would REALLY enjoy if some other religious groups showed up and sang something in, say, Indian (Punjabi or Urdu, etc). I think that would be fantastic. But I'm tired of always being solicited to join the Christian faith. That being said, I do, however, identify with the Christian faith, I'm just fed up with how evangelical it is in this society. That is great if you have your religion, but keep it to yourself. That's why I really like Judaism, they don't do evangelical work, and they don't care if you join their religion or not. In fact, they probably would prefer if you didn't. But that's why I like it, because they keep it to themselves and let the prospective followers decide for themselves and not have it thrown at them, like a McDonald's commercial.
Anyways, in the scheme of things, it's really not that big of a deal. But I prefer the lone guy with the guitar and Beatles songs to the Christian music, but it's still nice to hear a melody on a sunny day.
And those abortion pictures seriously made me throw up my lunch in my mouth last time I saw them. And I wouldn't have any qualms about getting rid of some abomination if I were raped by an uncle or something. But this is not the topic of this forum.
So, have fun singing, but you could add other inspirational songs that aren't necessarily Christian, but that are uplifting. I might even join in.

I dont care... let them do what they want, yes it is really fucking annoying to hear it. But whatever... ill just walk passed... :D
