I've heard of people having problems with playing music while navigating with Pandora. I've never been a big Pandora user, I hated the fact that I only got a limited amount of skips. I've used Last.FM since I got my phone. And today, I was playing music through Last.FM and navigating and had absolutely no problem. If you're having this issue with Pandora + Navigator, you may want to consider switching to Last.FM. Also this shows that this isn't a problem with 2.2 particularly because there are music players that don't stop when navigation voice plays. Now that we know Last.FM doesn't have a problem, is there a MUSIC PLAYER on the market that will play the MP3's we have saved on our phones without this issue?
