Are itunes songs free of sound defects?
ironically, when i got a new pair of premium headphones for my ipod, their sound quality only highlighted the fact that half the songs i have on there have beeping or popping sounds in the background. so are mp3′s purchased off itunes devoid of any noise inadequacies like this? do they not skip or have glaring defects like random alien sounds in the song?
They should not. However, just to be sure, you can preview the first 30 seconds of a song to check. If a song has poor sound quality, i’m sure you can ask for a refund.
