So, here's a good example of simplicity. Often, simple is better than complex. Phil Wickham's song True Love is amazing, but there doesn't need to be much in the loop to carry it. Just a little bit of bass and some synth to complement the band is enough to add without distracting. Hope you can use it, we've used this loop for about a year or so. It almost follows Phil's version exactly, but it's more like this one from Fellowship Church:
