General :: Trying To Use Pipe Or Awk To Work With MPlayer

I have a text file containing the URL I wanted for mplayer to play. Currently, I play those in commend line using the following steps:
1)cat playlist
2)use mouse to highlight the link
3)type: mplayer then click both left/right mouse button

I was hoping if I can do this in comment line without mouse. I've tried the following without luck. (assume there's only 1 address in the text file)
1) cat playlist |mplayer
2) cat playlist |awk '{print $1}'| mplayer
