Kodak gold (to my knowledge no longer made) and Mitsui gold (expect to pay a bit more than a dollar a disk online) recordable cd media are expected to last about 100 years (some people say longer, others have their doubts but all agree that these disks have much better dye longevity than typical disks). This of course assumes that the disk is taken care of. The big things are to keep the cd in a dark, cool area and DO NOT USE AN ADHESIVE LABEL on the cd. Depending on the label that can cut the usable lifetime of the disk to months. And of course don't physically abuse the disk.
Because the CD has become as ubiquitous as it has, it is as likely as any media format to still have players/readers around in 43 years but I'm hesitant to believe that they'll be at all common. But I would guess that in 43 years there will still be thousands of geeks of varying stripes with their 25 year old ultradvd player/drive that can also read blueray/hddvd/dvd/cd.
Making a standard audio cd (rather than a data cd with audio tracks) is imho the best solution for audio. This is a standard that billions of disks are pressed in, and is a well published standard. While it has less data redundency on disk (data cds have some redundent bits so that if a few bits go away the data is still there, audio cds don't) if an audio cd loses a few bits you'll just get a few holes in the audio stream and the cd player will recognize they're bad and smooth over them. If a data cd loses more bits than the error correction can handle it takes someone or something knowledgeable in data recovery (and possibly the specific file format) to get anything useful off of the disk at all.
