Sharing your music online is getting far easier and sites such as SoundCloud are creating a great service. I have yet to set up an account for Rusty Knuckles Music, but as I dig through their site more and more to test out the features, its pretty damn solid. The one element that stands out the most, is simply not having to download a track when someone shares it with you, you can sample it online before downloading. This makes it much easier to share and edit music as needed. The site was primarily geared towards electronic bands, but now its becoming more widely used in the rock community and is also a great place to build out an electronic press kit. Needless to say, we will be using this site quite a bit in the future as the label continues to grow at a rapid pace.
