Non-free material
To use copyrighted material where you do not have the permission of the artist you must make a case for "fair-use".  The guidelinea are at Wikipedia:Non-free use rationale guideline.  Basically, you need to place a fair-use template on the page of the copyrighted media (image or sound sample).  You have to do this seperately for every article the media is used in.  You cannot do this at commons, fair-use is not accepted there, you must upload the material to Wikipedia.  The fair-use templates can be found at Wikipedia:Template messages/Image namespace#Non-free images.  There is one specifically for album covers, as these are commonly used under fair-use.
