It doesn't matter what type of app you use to play the music. The problem is that you're trying to play an MPEG-4 protected file. You need to convert it to an MP3 and then it's easy to play. There are programs on the internet you can use to do this they cost around $40. Since you only have 1 album to convert you can just burn the songs onto a blank CD and then re-load them to iTunes as MP3 files off of the CD. The downside to this method is then you'll have to type in the name, artist, and album info for each song. I recently did this for a couple hundred songs when I switched from an iPhone to a Droid. It was a major hassle for that many songs and I should have just bought some software. If it was just one album it should be no problem.
