It was some classical music -- probably Tchaikovsky.
When CD players were first introduced, there were far too expensive for most of us. I predicted that if they didn't come down in price to below $200 each, they would never take off. The day I saw one advertised at a price below that, something like $199, I went and bought it. I personally didn't know anyone else who had a CD player at that time.
There was a big record store near my apartment. Out of the entire store, there was only one small table about 2 feet by 2 feet with CDs. The rest of the store was all records and tapes. The CDs that were available were all classical music -- there was no rock or country or anything else available on CD then. Most of the CDs that were available were from one specific series of recordings that were also available on records and on tapes. My first CD was probably one of those.
There were also a few random CDs that weren't part of the series. I bought one of English Hunting Horn music that I really liked. It came in a CD sleeve instead of a plastic holder and I lost it about ten years ago.
Sometime after that, my brother's company started selling data on CDs. At the time he had to send the data out to a company that would produce a master and then print CDs with the data. Production costs of each run of CDs was about $1,000 for the master and then about $1 for each CD printed.
Because of the high costs, he started to consider buying a CD recorder, one of the very first available. At that time, the price for a CD recorder was about about $60,000. I told him to wait and predicted they would come down in price pretty quickly so he waited a year and bought one for about $5,000.
