That right there is a premium quality radiator. Very nice craftsmanship. Lovely finish.
I like that jingle too. Only things I can think of is systematically checking the menu music playlist or using one of those "what's this song?" kind of apps, such as Shazam.
There is the chance that is part of an original score in which case getting the track may be difficult. And those apps only tend to recognise music that's been released. Good luck to you.
