We're all fed up to the back teeth with DRM's music, right? PlaysForSure not only doesn't play on your iPod, but you have to use Windows Media Player on your PC. iTunes music plays on your iPod, but you can forget about avoiding the use of the memory-hog iTunes app on the PC. DRM sucks, we all know it, but it's the only way to legitimately buy online music. Right?

Well, no. There are plenty of services that will sell you DRM-free music. But have you ever heard of any of the artists?

But thanks to an announcement this week, music retailer Amie St is making something of a buzz in the online world. Here's part number one - they sell DRM free music, so you buy the 192k MP3 of whatever it is you like.

Here's part number two - the site just signed a deal with Nettwork Music Group, a record label that represents major Canadian artists including Avril Lavigne, Barenaked Ladies and Sarah McLachlan. Barenaked Ladies is listed on the site right now for purchase, with other artists coming over the next couple of months.

Here's number three - the pricing is variable depending on popularity. Inspired by Digg, no doubt, a song, when first posted, is free to download. Free music! As people download it, it goes up in price - maybe it will cost a cent, then 10 cents, then 20 cents, whatever. Eventually, massively popular tracks cost 98 cents, which is the maximum cost for a track.

The upside to this is that there's lots of DRM-free, legal music at AllOfMP3 scale prices. You will also get to buy big-name artists that you can transfer anywhere, and that's a good thing.

Where one label leads, more are sure to follow - look out for more announcements about big groups on Amie St over the next few months, we suspect. In the mean time, take a look at the service and let us know your thoughts over in the forums.
