Google is going to step into the online music business according to The Wall Street Journal, which cites to sources familiar with the matter. The search giant is reportedly in talks with the music industry to offer a music download service that will leverage Google’s position as the top search engine worldwide. The service will be available both on the web for all platforms and on Android handsets. Look for the music search and download service to launch later this year with an add-on subscription option slated for early 2011. With books, tv, and now music, Google is making a big play for a bigger slice of entertainment revenue, no?
