Can anyone help me better understand Rhapsody payments?

I am completely stumped as to how the Rhapsody system works. It seems to me that the following is all true:

1) Using a free account, I can only listen to 25 full songs and can buy songs if I wanted to.
2) Using an “Unlimited” account for $13/month, I can play all the full songs that I want as long as I have internet access, understanding that none of the songs are actually downloaded onto my computer’s hard drive.
3) Using a “To Go” account for an extra $2/month, I can not only do what can be done with the Unlimited account, but I can do that with a mobile app for my iPhone. (now the part I’m really concerned about…) I can also apparently “transfer” the songs for free under the account to any MP3 player, including certain phones.

What else should I know and what. if any, of the preceding was correct and incorrect?
