Scanning system directory for files with NSFileManager traversing each
node ? I think it is not an efficient ... not to mention so many nodes
in an hierarchy you need to scan
A simple google search will help you in this regard, for starters
there are file handlers and spotlight guides could be your friends
Good luck

Briefly, scan the disk using NSFileManager. You can use -
enumeratorAtPath: to get an NSDirectoryEnumerator that will perform
the scan. Gather the results into some sort of data storage that
suits the purpose - a simple array would probably do, such as
NSMutableArray.
To display the results in a table, NSTableView hooked to a
controller e.g. NSArrayController that uses the above array as its
data model.
To play an mp3 file, the simplest way is to use Quicktime via QTKit.
e.g. [QTMovie movieWithURL:error:] followed by [myMovie play];
