I've purchased many songs from the iTunes store for my Apple Nano over the years and alot of them were purchased 4-5 years ago and have Digital Rights Manaegement software attached to them. I would like to convert them to MP3 to play on a different player. I tried converting them with Replay converter but get aloud buzz 1 minute into songthen it stops. Can I convert these songs using Replay Converter? Thank you.
