Not every "unofficial" recording is illegal. Taping radio broadcasts is widely common and allowed in Germany by the radiostations. They provide even a special free software for your PC (a radiorecorder) to record the broadcasts means for private use and private trading. Burning up to 5 CD-R is allowed. This is also free and costless promotion for the artists to trade such Items.
The artists playing at a radiostations here are payed from the station. We listeners pay a monthly fee to the government. So no "robbing the artist" is happening here und my county.
Think about that.
