With the Tune Recycler, you can send us your unwanted iTunes bottlecap codes and we'll use them to support independent music. Easy for you, and good for musicians.
Although the independent musicians supported through this project will undoubtedly not be the eccentrics espoused by beepSNORT readers, the sheer subversive act of moving indie music up the iTunes charts by way of PepsInc $$$ is interesting. This group also houses many other interesting anti-RIAA actions.
