Unlike iTunes, Audion will not burn a disk. It is very simply an mp3 player. What's important is that it'll play almost any type of mp3. You can create playlists. You can stream from internet. The latest version is version 3 & they still create a version for OS8-9. Tough question. Depends what you mean. iTunes is arguably easier to use. I always use iTunes (within OSX.) I use Audion just for those files iTunes can't recognise. I may convert these to aiff. I also occasionally encode mp3's using Audion. So for me it's just for the occasional use. But I use OSX 99% of the time nowadays. You can trial it out to see what you think. Quote: The Audion player comes as a free, totally uninhibited 15 day demo. After 15 days, not a single feature will be disabled - we just limit your sessions to 30 minutes. In short, we want you to use Audion as long as it takes for you to fall in love (and go legit!) For MP3 encoding (including streaming and recording), the demo is limited to 20 encoded files or 30 days, whatever comes first.
