OMG. I just listened to these songs, and they have a stronger connection to lucid dreaming than most of the songs mentioned above.
2 tickets to paradise.
Chaos Fantasy by ParagonX9 newgrounds.com/audio/listen/85046
Just about all of ParagonX9’s stuff
and that’s just about it.
I’m a musician and create alot of my own to find inspiration. I use alot of down-tempo type piano ballads in order to “slow the mind” and help meditate on subjects such as Lucid Dreams
What is Diamond sky, and power qeust. Is it Newage. I could download it, but I dont have speakers.
Power Quest is a very great power metal band. Diamond Sky is one of their songs.
Those links lead to the songs on YouTube.
Edit: Also DragonForce - Soldiers of the Wasteland
And DragonForce - My Spirit Will Go On
Creed - Higher
Because the song is about lucid dreaming 
LOL if I would listen to those, i wouldn’t fall asleep at all! XD
So no lucid ones neither!
Listen to this instead!

Lol I meant during the day
Also Dragonland - Contact
This one inspires me for the current LD4all quest
DragonForce - EPM
Also includes annotated lyrics
I recently had my first substantial lucid dream whilst listening to Led Zeppelin’s Houses of the Holy. Particularly the very good last track, The Ocean.
In the LD, I was actually hearing music (playing through my laptop). It was strange but beautiful, but my laptop display wouldn’t tell me what was playing (there was an area of opaqueness I couldn’t move over the part of the screen I wanted to see). Of course, my dream laptop probably wouldn’t be very accurate 
but I thought I’d give it a try. I wish I could listen to that music in RL!
Has anyone else heard music in LDs?
I have heard music in my normal dreams, but mostly not in any of my LD’s.
Echoes of War- The Eternal Conflict
Echoes of War- The Hyperion Overature
Echoes of war- Legacy of Terror
Well, I don’t feel like posting all of them. That album has 15 songs on it. They all average about 5-8 minutes. They are all songs that get my mind imaging landscapes, which helps me to sleep.
P.S. Yes, I enjoy dark dreams! Dark scary lucid dreams are the most intense for me. 
Hehe, lol. My types of lucid dreams are the types where there is lots of action. For example one of my favorite lucid dreams is my first one that I journaled, in which I made the school bus fly. It was quite something, and even the memory is exhilarating! Just the thought gets me excited 
Who all remembers Eluidate? That trance group. I thought they were really good I love trance.
I never realized that, until I read the lyrics. Now I need to download this song.
Blondie - Dreaming
Dreaming is free
I don’t want to live on charity
Pleasure’s real or is it fantasy?
Reel to reel is living rarity
Dream dream, even for a little while
Dream dream, filling up an idle hour
Fade away, radiate
Blondie (I’m Always Touched By Your) Presence, Dear
Floating past the evidence of possibilities
We could navigate together, psychic frequencies
Coming into contact with outer entities
Stay awake at night and count your R.E.M.'s when you’re talking with your super friends
Levitating lovers in the secret stratosphere
I am still in touch with your presence dear
In hopes of reviving this topic…
Power Quest - Wings of Forever
Power Quest - Beyond The Stars
Power Quest - Neverworld
