Is Google's new music subscription service/app any good?

I like music, and I have a pretty extensive collection uploaded to Google's servers. I've never been much into Pandora or other types of music streaming services. When Google updated their music app and it offered to let me try it's music subscription service, I turned it down, now the app doesn't show me the offer any more.

Am I missing something worthwhile here? I suppose I can uninstall the update to Google Play Music and see if the offer reappears. But I'm not sure if I should bother since I never used Pandora.

Do you people like it?
