It's simple drag and drop technology, so perfect for beginners to experiment and have fun creating music, video and photo slideshow mixes without a steep learning curve. However, there are advanced features such as beat-matching etc., so you can find a level to suit your capabilities. You can cut samples, remix tracks, change tempos, create slideshows, create & edit videos, record in directly from your mic etc. Check out the site for a full range of reviews.
We also provide libraries of royalty-free loops & beats that will help you in creating new and unique tracks - they're really cheap, so worth checking out:
