Doing other things whilst listening to a song on iTunes makes the music skip?

When I listen to music on iTunes whilst doing other things on my computer (like playing an online game or merely typing even) it makes the music skip and it never used to be like this. Would re-installing iTunes cure this?

You may just have too many programs running at once and it is using too much of your computer's RAM. For example playing a game can take up enough of the computer's RAM without having another program play music in the background. You can check by pressing Ctrl+Alt+Del, and check the CPU usage under Performance on Windows Task Manager. Hope it helps!

probably not - this is caused by the CPU (the engine of the PC) doing other work while the music is trying to be processed.
The PC is only capable of doing 1 thing at a time (instantaneously) so if there are other things demanding attention of the CPU it will need to skip the music for a short time.
The only way to cure this is to stop doing other actions that demand high CPU usage.

How much RAM do you have in the machine and what processor? Check your performance at those times too. This generally indicates that you have a bottleneck somewhere. Its generally going to be RAM or Processor and in some cases will be both.

you are doing TOOO many stuff at once. you have to limit your self and if its only one tiny thing then your computer needs to be updated. (computer = little box) there maybe an error in it. A computer specalist may help you find that error as the same thing has happened to me before.

basically cahnge that tiny box

Hope this helps
