			: The (probably easiest) trick to do that is counting backwards, from SDBSongList.Count - 1 to 0, and with step -1. See the example:
			<source lang="vb">
			For x = SDBSongList.Count - 1 To 0 Step -1
			If SDBSongList.Item(x).Rating < 50 Then
			SDBSongList.Delete(x)
			End If
			Next

What is the best way to use this method?

If I try to delete a track within a loop, the loop does not get the updated .count and it will go out of bounds..

example:

For x = 0 to sdbsonglist.count-1

if sdbsonglist.item(x).rating < 50 then
sdbsonglist.delete(x)
end if
Next

that is a realistic situation when you are checking a track list for certain criteria (ie rating etc) and you want to remove a track without creating a new secondary songlist object.
