selling stuff on the internet?

[M]

If I've written a book, can I upload the book to multiple e-publishing/selling sites without the companies blaming me? For example, I write a thriller and upload it to Kindle. But then I also upload it to a Chinese site, and maybe amazon. So there are now three ways people could find and buy my book. Anybody going to come after me for that? Do these companies claim exclusivity or are these arrangements non-exclusive? I am pretty sure they're non-exclusive but the agreement terms texts are so dense; I haven't found anything yet though but maybe I missed something.

SAME question about music/mp3s. If I made say a really cool song, and upload it to itunes, are they going to get pissed off that I also tried to sell it on another site? I think it's perfectly legal. From the seller's point of view, I could see it being unattractive, but that's as far as it goes. Am I wrong?

If you have the copyright to the book or music, you own the rights to it and can sell it via whatever channels are appropriate. For example, I'm a best-selling author and my books are available on Amazon as well as my own website and dozens of other places.

A company selling your products can only come after you if you have sold, given or otherwise transferred your rights to sell it - e.g. if you've given someone the exclusive rights to sell your product in a specific market, region or worldwide.

Otherwise, as long as it's a legal product to which you have the rights, don't worry if Amazon will get mad at you for posting it on eBay or elsewhere.
