Oh, the list is *very* long. I boycot copy controlled CD's since 2003 or so. Some of my friends do so, too. It's mostly EMI who is the bad guy, here in The Netherlands. Sony/BMG dropped copy control here last year, but apparently they want to lose money again.
To give an idea, on the top of my head:
Athlete - Vehicles and Animals
Audio Bullys - Ego War
Ben Kweller - On My Way
Chemical Brothers - Singles 93-03
Chemical Brothers - Push the Button
The Divine Comedy - Absent Friends
Doves - Lost Sides
Doves - Some Cities
Ed Harcourt - From Every Sphere
Ed Harcourt - Strangers
Fischerspooner - Odyssey
Gisli - How About That?
Goldfrapp - Supernature
Gorillaz - Feel Good Inc (single)
Idlewild - Warnings / Promises
Kraftwerk - Minimum-Maximum
LCD Soundsystem - LCD Soundsystem
Mando Diao - Bring 'em in
Mando Diao - Hurricane Bar
Phoenix - Live! Thirty Days Ago
Placebo - Once More With Feeling
Royksopp - Sparks (single)
Royksopp - The Understanding
Sarah McLachlan - Afterglow
Supergrass - Road To Rouen
The Ark - In Lust We Trust
The Magic Numbers - The Magic Numbers
Thrills - So Much For The City
Thrills - Let's Bottle Bohemia
Zero 7 - When it falls
Zoot Woman - Grey Day
Those are the ones I *know*. In a record store, I don't even look further when I see the copy control logo, and I curse the record company.
I even contacted a representative of EMI once, offering him real money for ANY kind of way in which he could have me play The Doves' newest record on my Sun Ultra 5. It has a cd-player which refuses copy controlled CD's, and of course it doesn't play WMA either. His final mail told me that EMI would "improve" the copy control in the future, but not lose it. I was deeply disappointed.
However, it seems that EMI doesn't add copy control to CD's with extra content (for example a video clip). They are real CD's. Some festival samplers aren't protected either. In those ways, I've been able to pay for at least some normal EMI content. I let my money vote.
I am sure there is still a market for CD's which were previously released under copy control. But I wonder who will re-release all those music that I wanted to have in these last years.
