When you download a free version of the program called Amarok on your computer, it's an obvious indication that you've purchased something. In the past, this might have been an error on your part and there would be no reason to worry about it. But when your system registry is running at full capacity, there is no way for it to recognize that you have paid for something. This makes your computer susceptible to damage and corrupted programs. This makes it difficult to recover from the problems that it has when you've downloaded a free version of the application. Since there are not a lot of people using Macs with a clean registry, it's only natural that most of them would be using this kind of software.
When you buy an application like Amarok, it goes into the registry. It starts gathering all kinds of information from applications that you have installed on your computer. Your Mac uses these entries to know what programs to load. The application actually stores a huge number of entries in the database and they can make the registry grows too big to run smoothly. The registry eventually makes your computer crash every time you start it up. It's not uncommon for your computer to have to shut down for ten minutes to an hour when you first start it up after a software repair.
If you're interested in downloading Amarok, there are also some differences between the two versions. The free version is a shared application between users. This means that if you've downloaded a free version and then decide that you want to download the full version, you will have to get it from another user. It is advisable to not download free versions of the software because you could just end up downloading another virus.
