Just adding on to this topic, This year I bought a sefira tape that was recommended to me, as i usually don’t buy for sefira cuz if its imitating music then whats the point?
Anyway this one (called kumzits in the rain) is very nice. Its just singing and harmony, no beats or any imitation of music whatsoever, and they are all slow songs that just get you in the sefira mood.
