, if you don't like it so much, don't use it. If you want a cloud-based archiving service that leaves your files untouched, use dropbox instead. Personally, I'm fine with 320kbps (better quality than most of what I ripped back in the old days when storage was expensive). I'm not fine with explicit versions getting switched for clean versions, though, but I expect that's a bug that will get fixed soon.
What I am not loving is the music manager. I've been running the upload for about 6 hours, and it's uploaded about 4700 songs. I don't know if that's fast or not compared to what it was like before scan and match, but it sure seems slow. I would expect scan and match to be much faster for the songs it has a match for. But the music manager doesn't give any info about whether scan and match is working.
I also don't love that it's not that easy to delete songs in bulk, and that there isn't a way to increase the 20,000 song limit (I'd happily pay), and that there isn't a clear answer about de-duplication. I have about 16,000 unique songs in various hard drives and USB sticks, but probably 30,000 total files as many of them have been copied from one place to another. It's way too much effort to clean them all up manually.
Any chance Google will open up the API to developers? I would love it if I could have a powerful service like Media Monkey that used Google Music as its library. That would solve many of these issues at once.
