Initial impression about Google Music Service

Last night I got my invite to use Google Music.  For those unaware, it is one of the three new cloud music services in which you upload your music collection to the cloud.  Once there, you access it from any Internet connected computer or Android device.  Initial impression is that you may want to set aside a lot of time for the initial upload to the Google servers.  To start, you download the music manager software.  It is the program that does the uploading.  You tell it where your music is and it uploads it.  Interesting enough, it uploads from anywhere.  I keep my music on a NAS (Network Attached Storage, Drobo to be specific).  It takes it from there.  Anytime you add music, it will automatically upload it.  It recognized that I had over 9000 songs and immediately started uploading.  8 hours later, it is up to 1656 songs uploaded.  Apparently this will take awhile.....  More to come
