Are you sure it's 48,000 KHz (or 48 MHz)? That's sound quality so high that you'll only get about 4 seconds' worth of music on it (uncompressed). I think you mean 48 KHz which is 48,000 Hz. In that case, it should play on most any player (provided the converter encoded it to MP3 properly) since 48 KHz is a standard sample rate (used with DVD's I think). If this is from a CD, there's no sense in using 48 KHz for 3 reasons: upsampling is mainly just deteriorates the quality (slightly), it wastes disk space that could be used for more songs, and beyond 40,000 Hz sample rate is beyond the frequencies of human hearing. If you insist on using 48 KHz, you'll probably want at least a 144 Kbps CBR (or 96 Kbps for ABR) for MP3, given my formula.
Some cheap speakers can go beyond 20,000 Hz pitch. One of my old sets seemed to support up to 50,000 Hz pitch (the tweeter) where, beyond that, it started to sound very weird and distorted.
There are uses for very high sample rates though. When editting the tune in a WAV edittor like Audacity, there isn't as much loss due to rounding errors (one reason why 32-bit floating-point is used).
Edit: As a side note, for 48,000 KHz, you'd need a 144,000 Kbps bit rate (to get about CD quality) for MP3 which is still so high, you couldn't get 45 seconds on it. You'd be lucky to get 2 songs on a DVD-MP3 CD though.
