Is there a trope for really slow, peaceful, relaxing music, such as you'd, say, do tai chi or yoga or stretching exercises to? I get this from Set the Controls for the Heart of the Sun and use it as a warm-up sometimes.

Related: Do we have a trope for when you meet a band through a song that sounds really cool, but then when you try to lay hands on media from the band (say through the library), you find that the song is nowhere to be found - it may mean a lot to you, but it was hardly worth notice to anyone else, or something, so good luck finding it except maybe on You Tube. (I've had that experience... same song.)
