I don't even think you're right. Track for track, CDs (outside of rare instances, and then usually only for a short period of time), were barely more expensive than the the iTunes tracks.
You quote $30, but that is not really how much most CDs cost. Let's use $15 or $20 as a more average number with an average of 12 tracks per CD. So what, you're paying maybe $1.50 or so per track?
Well iTunes is 99 cents to $1.49 so it's really not a huge difference. What the digitial age did is bring about the ability to buy single tracks of any music without needing to buy the rest. It wasn't really the cost cutter you're implying. There is no such thing as "fair" pricing. Pricing will be whatever the market can bare, that's capitalism and that's the fair price. If people thought it was too expensive back then, they wouldn't have bought CDs and the companies would have had to lower prices. They obviously didn't feel that pressure because people bought them. Maybe you couldn't afford it, but that was not the issue.
As for your supposed "right" to music, that's garbage. You do not have a right to anything other than to live. If you can't afford the music, it doesn't give you the right to steal someone else's work. There's tons of music in the public domain, or the radio, or if it's so important to you in order to live, learn how to sing or play an instrument.
Don't try to defend your theft, it just makes you come off as more unethical than you already are. If you want to steal music, that's your choice, but don't try to make it sound like you were doing the right thing.
