Development of the leading MP3 software, SoundJam, is to end, its publisher Casady & Greene announced yesterday.

The company will cease publishing the MP3 software from June 1. The decision is thought to be at the request of SoundJam's original developers.

Apple's iTunes is partially based on SoundJam. Apple hired the application's developers to help develop iTunes.

SoundJam developers are still working on iTunes. Casady & Greene will maintain support for SoundJam after June 1.
