Recent changes to Prime music are terrible. If I minimize the window it loses my playlist. It continually prompts me to buy the unlimited version. Also I no longer have access to music that I've already purchased. Update: Still bad, crashes, and always wants me to pay more. I do not recommend. Update: Five years later and this app is still terrible. Where does my Prime money go to? Obviously not to update their software for me as a user. App still doesn't access some music I purchased.
