Do not buy Coldplay's latest album, X&Y, or any other CDs by EMI because they contain copy-control technology that will basically prevent you from playing the CDs properly on any systems other than your home stereo. If you play it on your car stereo, or import it into your portable mp3 players, the music will skip or you will hear static every few seconds.
Copy-control sucks!
There are many ways to listen to your favourite bands..*hint hint*.
Until the music companies stop treating legal music buyers like 4 year olds, then they're not getting a single cent of my money.
