Awesome site if you guys haven't found it yet. It's a russian site, so I assume that's how they get away with selling songs for so cheap. You basically deposit some money in your account and then just start downloading songs... I've gotten entire albums for less than $2!! Songs normally run between 7 and 15 cents! A guy at work told me about it and I'm really hooked.
The best part about it is that once you pick your songs, you get to pick the format and the bitrate at which they'll be encoded... and then they literally encode them on the server before placing them in your "downloads" section of your account. Normally the encoding process is very quick (less than 20-30 seconds in most cases, unless the server is overloaded and that only happened to me once). They have various formats... wav, ogg, mp3 and a few others. The price also changes slightly depending on what options you pick... the prices I quoted are for mp3s at 192kbps.
What's also cool is that they have their own explorer program that downloads the latest catalog so you can browse the selection offline. Then if you want to preview a song, it taps into the net to grab the preview(which is actually the full song... only at a crappy bitrate).
Check it out... I think you'll love it.
