iPhone playlist

[Dylanj04]

So I was wondering about making a playlist on my iPhone 4 - latest firmware - and I was looking around and can only find going into the playlist section and selecting songs individually for the playlist.

What if I want to just throw my iPhone on shuffle and a song I like
comes up? It seems like such an overlooked idea to just have an "add to playlist" button on the screen. Unless I'm completely missing something, is there a way for this to be done? With or without jailbreak?

Thanks guys.

I set up a smart playlist in iTunes, I set it for a certain rating minimum and number of plays, so when the info syncs, my playlist is created/updated that way.
