No doubt (my own reading of it here) when Moses gave them the commandments, they questioned it all and as a result ended up being restrictive again. After a very long spell of self rule and free to do as they liked (save to call the Pharaoh god) to be suddenly given strict commandments was just too much for them. They rebelled! Added to that, the stern nature that was Moses made the religion a real 'chore' no doubt.
Hence, as sis Muslim Woman puts it, what was needed for that time was a 'sweet and gentle' reminder for people to 'reconnect' with Allah, and the sweetness of David's voice singing the songs of praises soften the hearts of the Jews after the shock of the laws given by Moses...
Again, this is just my interpretation.
