Ipod touch: Music stopping when browsing internet

Hi,

I bought an Ipod touch at the weekend and was playing with it for the first time last night. I was listening to music and then browsing the internet over wifi using the safari browser.

Has anyone come across the music stopping/freezing when using safari or browsing the internet? Have i got a faulty ipod? Is there anything i can do to find the cause?

Please help,

Thanks in advance,

Edward
