And what are you suggesting?

Currently, we use playlist item IDs, which are weak handles, which are
buggy. There is a warranty that you won't get a dangling pointer from an
item ID. But if you save the item ID for later retrieval, you may later get
another item (due to ID wrap-around), or no ID at all. In fact, if things
wrap around, hell breaks loose because we may assign the same ID to more
than one item...
