Marcus, you just need to remove all the letters, etc of the YouTube URL until "v=". It's the letters/numbers after that, which actually show the video. Quote mine as an example and you'll see what I mean.
Less known song, the great thing about Megumi is the sheer volume of songs she has released in her career. I've always been crazy about the synthwave sound that cropped up in the 80s, which was still popular in Japan in the 90s and I can still hear some traces of it in modern Jpop once and a while. Not sure why Americans want to forget about 80s music so much because that shit was awesome.
