I bought an album through iTunes on my Macbook. I then synced my iPhone to get the album on my phone. The album is there but about half of the songs on the iPhone have duplicates. There are 10 songs on the album. Songs 1-5 have no duplicates. Songs 6-10 have duplicates. The songs in the album look like this: 1-Perth 2-Minnesota, WI 3-Holocene 4-Towers 5-Michicant 6-Hinnom, TX 6-Hinnom, TX 7-Wash. 7-Wash. 8-Calgary 8-Calgary 9-Lisbon, OH 9-Lisbon, OH 10-Beth/Rest 10-Beth/Rest Any ideas how I can fix this? And how can I prevent this from happening in the future?
