Songs Sometimes Play
 

Lets say i have a list of songs, some songs get skipped and some songs don't get skipped. I close the winamp, and i then go to the song that got skipped and i right click on it, then tell it to play in winamp and it plays. I go back to my previous list and the song plays, but other songs still get skipped and will only play in my list if i do the same thing to that song that i did to the previous song. Whats going on, and how can i stop it from happening every time.
