As a complement to the adjacent comment thread on Shoegaze music, I find a similarly dense, soothing, blanketing effect from some recent noise/drone music genres (especially on good headphones, or out loud with a subwoofer), for example:

The pulsing deep noise of Tim Hecker's Piano Drop:

The gradual crescendo to a wall of noise in Abul Mogard's Like Water:

Conflicting tension + blanket of sound in Siavash Amini's The Wind:

NB: All of the above have a significant low frequency component that may be missed on desktop speakers or low quality headphones...

Everything by Carbon Based Lifeforms is also very soothing, albums like Interloper, World of Sleepers, Hydroponic garden also really give me that feeling and with just a bit more beat and melody that I love.

The first track of Interloper just soothes me real quickly:

For those wanting to generate some sounds like the above, I made what is effectively a noisy synthesizer / visual demo a while back that can be played note by note on a PC keyboard (or will play itself if left untouched, see attached readme). But to get it into "wall of sound" territory you need to hold down the up arrow and/or space bar for quite a while to speed up the bike until the visuals start distorting:

How about Dream Pop from groups like Still Corners and their song The Trip?

I find it very relaxing. I like how the beat seems to subtly change in different parts of the song - it could be an auditory illusion.
