I have ALL of my online services through Google... music, email, calendar, maps, contacts, chat, pictures, social networking, android phone, etc... It all works great. Rarely do I encounter an issue; and if I do, it always fixes itself automatically with a couple weeks max.
There are zero Linkin Park songs available on Google Music. I've got tons of music in my Google library that I listen to every day. But I have no songs from my favorite band.
Please (if you can) put all of your albums on Google Music :)
Yes I know I can buy MP3's from other companies, but I'm holding out (since I am committed to Google's services and products). I actually have nothing but trouble with Apple products. So, I just don't buy them. I don't really care for for Amazon software.
