I used all the CDs for my wedding, from the entrance to the end roll. They're full of classic songs, so I think they're all easy to use! These are popular CDs, so they were a bit expensive, but I'm selling them for less than that! Some are ex-rental copies, so there may be some scratches, but there are no issues with playback. You're welcome to resell any CDs you don't use. Artists included: EXILE Che'Nelle wacci Ryokuoushoku Shakai Kera Kera Uru Bruno Mars Novelbright Yuka FRUITS ZIPPER sumika
