I used a system media player - no problem with music.

Actually - no problem with Internet Radio stations too even WiFi or 3G.

BTW, I browsed while listening my N900 and I don't see any problem.

Can you point us with link to "we found it to be a very common problem" (I mean - in N900)? It is interesting to me.

But I use system media player because it has a different priority in comparison with another half-cooked players.
