Bests & Worsts Reviews from Amazon

I cannot see the purpose of a music player where you have to log in with a password every time you want to listen to your music... The final straw came a week or so after I installed the program, having tested it once and never touched it since. My PC was running really slowly, and investigation revealed 2 instances of a process called something like "amazonmusichelper" were running, each taking up nearly 40% of the capacity of my 6-core processor. I don't need help with my music, thank you very much. I certainly don't need or want any program which will activate itself and use up all my CPU cycles, without any kind of permission or notification. The player was uninstalled and trashed.
