I beseech you

Does anyone have any ideas for studying lyrics with a rather remedial class of 11th graders? I promised them this assignment before spring break, and if I don't follow through on Monday, there could be a mutiny. Of course, I told them about it without thinking through how we would study their chosen songs, which are largely about hard core drug use (a 50 Cent ditty about heroin), recreational drug use ("Wrap it Up," a double entendre for both rolling a joint and fornicating), and whatever other kinds of drug use there are, without degenerating into a session of "listening to CDs." (No one in this class has an ipod, thank goodness.)

So, the parameters are: they get to choose their songs, I get to veto the really bad ones, and I need to make them study the words and write about the songs in some way. The goal is to learn that understanding and analyzing how language works can be fun! And you do it everyday without realizing it! And knowledge is power! And if they are inspired to lift me up at an assembly while singing "Lean on Me," so be it.
