It doesn't really make sense for a ListView to have it's height to wrap_content since a ListView allows you to put in more items than will fit on-screen. It can have a height set to a fixed value, e.g. 300px or 200dip, but not wrap_content.
You should never really need to stack lists vertically on-top of or within each other (there are a few exceptions to this, but as a general rule). You should read up more on the ListView component and layout params. Just use different types of list items (a ListView can have many different types of items) and different levels (in theory you could extend ExpandableListView to have as many tiers/levels as you wanted). If you stack ListViews on top of each other (with a fixed height), you'll only be able to fit 5-7 in on a normal device, and each one will only be able to show about one item at a time. What you probably want is an Expandable ListView, with the group items showing the Album/Artist name, and then when these are expanded they will reveal all of the songs in that album.
