For years (and years and years and years) I've read that meditation is good for one's health. BBC (radio) had a short piece on, last night, tauting the benefits - among which is lowering one's heart rate. My heart rate has always been higher than most people's. At age 12 during a first aid class, at school, we learned to take one another's pulses. The kid who took mine could not believe what he was getting. Our teacher took my pulse and verified that it was 112 beats per minute.
"Normal" pulse rate for me as an adult has been 80-100, unlike my exercise partner who is doing well to get her pulse rate up to 85 or Elder Brother whose resting pulse rate is under 50. (In stress testing 10 years ago, my pulse reached 166, 11 minutes into the testing - before the physician stopped the procedure.) Getting to the whole point of this posting: the reporter on BBC reported that the most restful musical piece ever recorded, "Weightless" is available online, and suggested that listeners try meditating to it. Below, a video of that piece is embedded. Me? I find it annoying and boring, probably raising my pulse rate! The time duration is 8 minutes 16 seconds.
The embedded video of Beethoven's Moonlight Sonata, below, (or anything by Yo-Yo Ma) is more soothing to me. Play time is 60 minutes.

Stu has suggested another relaxing piece. I don't recall my first exposure to the performance, but I can't fault Stu in his reasoning!
