Not a big fan of dubstep, but a light sort of dubstep I like is Pretty Lights, and you can't really go wrong with the Excision Shambhala mixes

Son of Kick - Playing The Villian .
If you like dubstep, try the oldies. Search for Rusko, Joker, and the others.
For chillstep, i recommend 123Mrk. Especially the track called Untroubled.
I listen to Kryptic Minds to chill, but it's actually psystep, but can work as chill too :)
Hope I helped you.

Also Klaypex - Lights, and Ellie Goulding - Lights (Bassnectar Remix).

Strange Talk - Falling In Love (Draper Remix)

Till Death - Last Wish

Loefah - Mud

A random DJ mix

I listened to both dubstep and Chillstep. Here are some good tracks IMO:

Retro City - Adventure Club

The Signal - BertyCox

Also, you can go here, there are DJs in there that often have some great tracks.

I like that one that goes 'WubWaWaBwubWa-wa-wa-waa' :-P

sorry, I have nothing constructive to add to this conversation.

Feed Me - Strange Behaviour (ft. Tasha Baxter)
Feed Me - Blood Red
And nice giveaway btw :)

Nicky Romero -Tolouse

Bingo Players - Rattle

Dimitri Vegas - Mammoth

Not dubstep, but still awesome

Here, take THIS track!

"dubstep" "chillstep" and "lightstep" are all exactly the same. It just sounds stupid to give them different names.
Really really stupid.
