I'm not sure if this is relevant, but beyond disruption to the meal service, I have not heard the boarding music nor landing music being played on all 3 of my flights since the SQ321 incident. I'm not sure if this is consistent across all the other flights (please reply to this), or whether it is just me being unlucky as I really do enjoy the SQ boarding and landing music a lot.

Just to add to the plethora of experiences on board since the incident -

SQ308 (EY) - Second meal service was served approximately 5 hours from landing in London.

SQ345 (EY) - Second meal service, contrary to most of the experience here, was served approximately 2-2.5h before landing. However, in the midst of the service, the seatbelts sign came on until the aircraft was nearly at Kuala Lumpur. As such, the cabin crew announced modifications to breakfast service for those that had not received their meal trays - they served yoghurt, fruit, bread (with butter), and a beverage with no main dish. The crew apologetically went down the aisle quickly serving the trays while coining the service "continental breakfast". But nevertheless, kudos to them for actually serving breakfast to most of the economy section(albeit modified) when there was about an hour before landing, especially since KL service flights only offer beverage service. However, the experience with the seatbelt sign does echo those above; one such incident was that, the moment I had entered the lavatory, the aircraft experienced a slight wobble. Accordingly, the seatbelt sign was turned on. However, by the time I was done peeing and washing my hands, the seatbelt sign had been turned off.

SQ122 (EY) - Beverage service as always for the KL flights, but it appears that the crew were even more rushed with their service. However, it has to be said that, on this flight, the weather en route was horrible - clouds everywhere, weird holding patterns etc. I guess the weather played a part in inducing their rush.
