does "swept away" have any special meaning in Engl

for example,there's a movie called "swept away";Yanni's great hit "swept away".does the phrase have any special meaning here?

Swept away is an idiomatic phrase that means to be emotionally overwhelmed; by love, by music, by an idea -- that sort of thing. it's usually positive.

Being swept away by a tidal wave, swept up by a tornado, or swept out to sea is another meaning; as you might guess, it means to be picked up and dragged away by forces beyond your control; this is usually a bad thing.

So you have to pay attention to the context to know what the speaker means.

Oh, and you can also be swept off your feet by a romantic person -- swept is a pretty multi-use word!

thanks for the very usefull reply,Urel.
and i still have a question,if i wanted to descript that i'm deeply touched by a certain song,whould "i'm swept by this song" without the word "away" be nice?or saying "i'm swept away by this song" will be much better?

Use the "away". "I'm swept by the song" wouldn't make any sense to me.

<Im swept away by this song>

It's like you are amazed by the song (usually postive).

You can probably use: "I was swept by the song"
'I am swept...' sounds odd.
