I've been waiting for Google to do scan and match. Now it won't be so labor intensive. The best part it's free. The 2nd best part is that it STREAMS my music instead of trying to download music to my phone taking up space and making it difficult to remove it (talking to you iTunes Match). That 2nd part is the reason why I didn't renew my iTunes Match subscription this year. The first 20k songs is free. No word on if you can pay for additional space.
