Napster - Is it Safe?

One of my clients wants to install Napster on one of the PCs in his office.
This PC is one of about 15 networked computers with XP PRO sp2 installed.

He wants to use Napster to download * only * and not share any of his
Any input as to how 'safe' this is and whether/why he should avoid this
software is appreciated.
