can't hear anything?New scandisk sansa+

Just got a scandisk sansa clip+ from Amazon and have charged it think I’ve put some music on but can’t hear anything.The screen reads music but can’t get it to change to anything else .From my pc it appears that the scandisk came loaded with some music but can’t seem to access that either.None of the pictures on the website are the same as mine eitherHelp

Thank you very much The instructions are poor and the plastic cover very hard to see but should have thought of that.Now we get to enjoy the scandisk
