From everything I've ever seen/read Joaquin is a very private and pretty shy person. He doesn't enjoy interviews much like Heath Ledger. (

) How do you know he has a substance abuse problem?
Joaquin is one of my absolute favorites. I'm still bitter about him not winning the oscar for Walk the Line! I thought he was robbed. Anyways, aparently he really got into music during that (walk the line) as he learned how to play the guitar. I have no problem with someone saying they're leaving one profession for the next. You gotta follow your passion. Though I will miss him on screen perhaps now I'll be able to catch a live show instead!
