Good techno/electronica, or trance?

Hey i'm looking for some techno, and some electonica and maybe some trance to add to my music library. Got any ideas?

Armin Van Buuren, Above & Beyond, Oceanlab, Ferry Corsten, BT, early Tiesto, Mat Zo, Aly & Fila, Markus Schulz, most of the Anjunabeats CDs, and the yearly A State of Trance compilations.

Daft Punk. That is all.

Daft Punk (obviously), Animal Collective, The Postal Service (and Dntel), and Miike Snow are all pretty cool stuff to listen to.

Aphex Twin, Squarepusher, Daft Punk,  Ratata , The Fucking Champs, NIN Ghost album, Coldcut, UNKLE, Kid Koala,  DJ Starscream

KRAFTWERK!!!

Any Ed Banger artist, Mr Oizo, Justice, Feadz, whatever you can find. 

Wipeout HD OST
 
Some great music.

Those are some rather unspecific as well as separate genres - but still, I'd recommend Fluke (especially the 1997 album Risotto, it's awesome), µ-Ziq, Autechre, Fever Ray, Psychic TV (one of the inventors of the acid house genre), Eat Static, Visions of Excess and late 80's/early 90's Clock DVA.

Sabrepulse, Dieselboy, Kaskade, Perfume, J Majik and Teebee are all good. Pretty much anything from the Wipeout games is good too, as someone has already mentioned. I also really love the Ridge Racer 4 soundtrack, so give that a shot if your interested.

Deadmau5.
     
  

Massive Attack

Listen to Blaqk Audio. Unless you hate the singer from AFIs voice, in which case listen to it anyways cuz its an awesome electronica/synthpop band.

Justice - Planisphere. it's a 4 part thing that they made but it's a little hard to find. 
Also you should have checked out all their other stuff.
    

To Record Only Water For 10 Days is a pretty good electronica album.

Maybe you would like some EBM? Here's some phosgore.   

A few off the top of my head that are some of my favourites: Marcus Schossow (prog. trance. His album, Outside The Box, is godly), Noisia (mostly DnB, but they have some good electro tracks), Stephan Bodzin (electroish house), Wolfgang Gartner (electro house). (Also, not a huge fan, but The Chemical Brothers, since no one has mentioned them.)
 
But anyways, only checking out a few specific artists isn't a good way to get to know electronic music (well, for trance and house at least). Usually, the best tunes are made by some of the "smaller" producers that are not mega superstar DJs (like tyDi, Arnej, Anhken, Jochen Miller, Leon Bolier, Wippenberg, DJ Eco, Arty, Mr. Pit, W&W, Gareth Emery and MANY more, I could go on and on), but then again, they are played by the big DJs on radio shows and live sets. So giving radio shows like Global DJ Broadcast, A State of Trance, Tone Diary and BBC Radio 1 Essential Mix a listen is a nice way to find good choons, but also looking around at online stores like audiojelly, beatport etc.

Aphex Twin, like others have said, is a great place to start if you are unfamiliar with the genre.  Selected Ambient Works is a good first album. 
 
If you are looking for something a little less intense, musiq (the mu is the greek letter), Boards of Canada, and Ulrich Schnauss do something that is a little more chill/ambient. 
 
Also, I found some good stuff by going to sites like last.fm and pandora and entering "IDM" in the station seed box.  Last.fm has a very good electronica community, you could ask there.

So this is a relatively old track, but I think it's really easy to listen to.

I just posted some of his" love" songs that I could remember.  PM me if you're interested in his Discography.

I listen to Daft Punk, Justice, MSTRKRFT, The Crystal Method, Royksopp, Pendulum, Prodigy and deadmau5 These are mosty Electronica tho.

It's really interesting to see how intensely varied people's definition of "electronica" is.

GRUM - Heartbeats 
  
It's an amazing electro-disco album, perhaps the best this year.
  

I'm going to assume the lack of Daft Punk mentions in this thread is because people figure the OP HAS to known of Daft Punk  unless he lives in a cave.
 
 
........right?

Oh and a few great tracks!
