Okay, I got the Samsung Impression for christmas and I know it better than the back of my hand.
If you have windows media player (which is what i use) you hook up you phone to your computer. Windows media player will show it and it will come up on your screen. Name the thing samsung impression. Then sync your songs to it by creating a sync list. Or of course, you can play them off a radio and record them...it doesn't turn out too bad.
Toodles!!!
HOPE I HELPED!
