How can I play music on my iphone without downloading itunes?
 

I don't want to download all 5-6 iphone programs, etc. to download the music to my phone. So how can I play music on my iphone without downloading itunes?

Is there and app or a single program?

Pandora app

You can use the "Files" app (cheap - 99c IIRC) which will let you transfer files (any type) via wireless network. If you transfer MP3s, it has a player built in that does shuffling, repeating, etc.

About half my music on my iPhone 4 is added via iTunes from my Windows machine at work - the other half is in "Files" and uploaded from various linux boxes, etc.

Download itunes (free) and then use it to find the music already saved on your computer, there's a command along the lines of "open" that imports your music. Probably 90% of my music is either ripped from a CD or downloaded before I had ever heard of an iPhone. It's only one free program, and there's no requirement to get set up with an account.
