Not at all, do a quick Google, it's not an isolated issue. Funny enough, the first result is from this very forum. Also, if it was an isolated issue PowerAmp wouldn't have built in settings to help prevent this issue.

It's all to do with the CPU. If the CPU is only allowed to run at 200 MHz of course it's going to struggle playing audio that is of half decent quality because it won't have enough processing power to load the data.
Modern electronics shouldn't skip and that's why this issue is so ridiculous. Unless you root your device to install setCPU, you can't change the minimum MHz for the CPU. It's absurd one would have to root the device just to get proper audio playback.
My last chance is tomorrow. I've had both PowerAmp and Player Pro skip today so in PowerAmp I enabled both audio skip settings. I'll spend all day tomorrow with these settings enabled, but my impressions of Android have gone from absolutely perfect and the best OS to below satisfactory.
