iTunes and Napster purchases - problems in the future?

[anonymousbird]

I get quite a few tunes through napster and they are held in my iTunes on my Mac which is all great and works fine, they zap to my phone and ipod no problem.

However, and perhaps I am wrong with this, but I have a vague recollection of someone saying that if/when i come to replace my Mac, that anything not bought through itunes can be difficult to transfer across.... anything in this before I go and obtain a whole lot more through Napster?

And if you want to know why i am using Napster not itunes to buy, it's because I have LOADS of vouchers for free downloads from Napster!

TIA.

"I have a vague recollection of someone saying that if/when i come to replace my Mac, that anything not bought through itunes can be difficult to transfer across."

I can't see why their would be any kind of a problem. You'll just drag them out of iTunes onto something the new computer can see and then you drag them from that onto iTunes on the new machine.

So download away :)
