Lol please. We offer college credit if people want to get college credit. I did 6 months unpaid with P+P and now I'm the (paid) label manager. Another intern came from Chicago, ended up getting hired full time, now lives here. It's not like we take in naive young people then work them to the bone and spit them out starving and poor. At the very least you get an awesome add-on for your resume, a letter of recommendation from a guy who is pretty well known in the industry, and the cool experience of working for a label and drinking a lot of beer.
I'm not speaking poorly about P+P, I meant unpaid internships in general. Many companies today create unpaid internships to pawn off work to college kids and call it "a chance to network, build a resume and get real world experience" when it isn't much more than busy work no one else wants to do.
By that description of your experience and the original post, this internship is borderline illegal. I would recommend looking at the U.S. Department of Labor's Wage and Hour Division letter about what is a legal unpaid internship (http://wdr.doleta.gov/directives/att...GL12-09acc.pdf
These two particular points stand out,
3. The trainees do not displace regular employees, but work under their close
"We want the type of person who can take on a project without being micromanaged; a person who can multitask without being taught how. "
4. The employer that provides the training derives no immediate advantage from the
activities of the trainees, and on occasion the employer’s operations may actually
"The fall interns will get the opportunity to work in big-time projects..."
Not trying to be a dickhead, I'm just giving you the heads up on the legality (these points could of course also apply to a lot of unpaid internships out there, thus bringing me back to my original statement that unpaid internships are bad).
