Looks like traditional music got another kick in the pants. Strategy Analytics is forecasting that digital music sales will surpass sales of CDs and vinyl this year. Those digital sales include streaming services like Spotify and Pandora. We saw recently that teens are using Google's Youtube to get a lot of their music, too. Add in Sirius XM and lingering terrestrial radio, and there are fewer and fewer reasons to own your own music. Fool analyst Anand Chokkavelu is an audiophile himself and has been hanging on to his CD collection, Yet, he hasn't bought a CD in more than a year. The combination of Spotify, Pandora, and Sirius XM has been scratching that itch. He explains in the video below how the cloud is replacing the CD and what that means for investors.

Another hotbed space (and where many are now getting their music) is mobile. The mobile revolution is still in its infancy, but with so many different companies it can be daunting to know how to profit in the space. Fortunately, The Motley Fool has just released a free report on mobile called "The Next Trillion-Dollar Revolution" that  tells you how.

Hundreds of thousands have requested access to previous reports, and you can access this new report today by clicking here -- it's free.
