** 1/2 Cash Money Millionaires, “Baller Blockin’,” Cash Money/Universal.

This soundtrack comes from one of rap’s most popular and influential rhyme families, as well as some of its friends, but the results are uneven. For every standout cut (UGK’s “Family Affair”) there is a monotonous track (TQ’s “I Got to Go”) to match. Mack 10, Juvenile and Lil’ Wayne appear on some of the street-centered collection’s better songs.

Albums are rated on a scale of one star (poor), two stars (fair), three stars (good) and four stars (excellent).
