Imogen Heap - Speak for yourself
It has an incredible clean sound to it. There's like 50 layers of vocals and shit.
Also, check out Timberland and stuff by Justin Timberlake.
Definitely Speak For Yourself. Considering she produced it all herself in her bedroom and blah blah it's pretty amazing.
Gotye is an Australian artist and his album 'Like Drawing Blood' is pretty damn well produced all round - it's very well layered music which is all leveled perfectly on a sonic level and such. If it was just a studio album it wouldn't be that interesting but considering he did it all himself it has this cohesive, full feel like few other albums I've heard do. Here's a link to the video of one of the songs:
