But I'll kick it off with this classic choice:

Google Is Awesome...

Here are a few sites with playlists.  Enjoy!

You can down load his albums from iTunes.  The two best are Cathedral and Conundrum.  The best one for sex is Plugged.

The conventional wisdom in the scene is that the best songs for play parties are generally without lyrics (distracting) and have tempo/beats that work well with the rhythm of your flogging, spanking or other type of play -- but factor in warm-up and cool-down in your play list, too.  The Buddha-Bar collections are pretty awesome.

Disregarding everything I said above, you can't go wrong with Depeche Mode.

Just put these two on a loop: WHIP IT (Devo) TAINTED LOVE (Soft Cell)

Tainted Love -

Sometimes I feel I've got to run away
I've got to get away
From the pain you drive into the heart of me.
The love we share seems to go nowhere

And I've lost my light for I toss and turn - I can't sleep at night.

Once I ran to you
now I'll run from you

This tainted love you've given -
I give you all a boy could give you.
Take my tears and that's not nearly all - oh
tainted love - tainted love.

Now I know I've got to run away
I've got to get away.
You don't really want it any more from me -
To make things right you need someone to hold you tight

And you'll think love is to pray but I'm sorry I don't pray that that way

Once I ran to you,
now I'll run from you,

This tainted love you've given -
I give you all a boy could give you.
Take my tears and that's not nearly all - oh
tainted love - tainted love.

Don't touch me please - I cannot stand the way you tease.
I love you though you hurt me so

Now I'm gonna pack my things and go. Tainted love - tainted lov

I like no music. Of course this is just a matter of opinion but I have always found soundtracks distracting.   I am very much into the hypnotic effect where being able to fully concentrate on the voice and voice suggestion is paramount.
Then again, maybe it is that I have just not yet learned how to induce such a state while music is playing in the background. (I learn all the time by reading these posts, thank you.)

Rule thumb is no spoken English words...very sexy music you don't have to focus on consciously which you listen to through head phones.  Very relaxing!!
