Welcome to the site
mmm studio studio, why art thou cut the clip while editing.
Yep it cuts the imported clip down evertime you add a new clip to your story board.
so for example you make the title add a clip, then add the mp3 sound track, then add another clip... oops the sound track you added then finishes at the end of the last clip you added.
Easy, just left click the end of the mp3 sound clip and stretch it to your right.
Hope this sorts the problem out, i have also found that it will not play some mp3 files ? no idea why, maybe they are locked to only play with a lisence ?
Hope this helps,
Always use files direct from you hard drive.
