I am shopping for Maxell CD-R 80 Minute 48X 700MB at Amazon. I am confused by the different offers. I see several packs of 50 w/different numbers, like one has # 625156, another has # 648250. They have different packaging. I had a small project converting a cassette tape to CD at a recording studio. My guy separated the songs into tracks, then burned me 2 CD's. He also dumped the work onto a flash drive for me. I plan to burn a few copies for people I know. Is some of the stuff just old, and some newer? Would appreciate advice as to what to buy. Some people tell me CD's are not going to me made anymore. Well Vinyl is coming back, and somebody is beginning to manufacture cassette tapes again.
