oShell = createobject("shell.application")
loDir = loShell.Namespace(lcDir)
lofile = loDir.parsename(lcFile)
lcArtist = loDir.GetDetailsOf(lofile,16)

see http://technet.microsoft.com/en-ca/library/ee176615.aspx for the list of properties and their index number.

Other way is to read last 128 bytes of the file.
They should start with TAG,

lcDetails = RIGHT(FILETOSTR(YoruFile), 128)
IF LEFT(lcDetails,3) == [TAG]
   ? "tiltle", SUBSTR(lcDetails,  4,30)
   ? "artist", SUBSTR(lcDetails, 34,30)
   ? "album" , SUBSTR(lcDetails, 64,30)
   ? "year"  , SUBSTR(lcDetails, 94,4)
