Help, what is wrong ?
sprintf(command,"open %s type waveaudio alias mp3",filename);
mciSendString(command,0, 0, 0);
mciSendString("set mp3 time format samples", 0, 0, 0);
mciSendString("play mp3 from 1 to 10000", 0, 0, NULL);
This code does neither play a mp3 file nor a wave file.

Fortune! finally it works with wave files. (the end range 10000 was to high for my testwaves).
But mp3 files wont play.
I use W2k and have the "Frauenhofer IIS MPEG Laver3-Codec (advanced) 1.9 build305" installed and working.
I thought i could play any multimedia files when the propriate codecs are available.
If I am not wrong, MCI can play .WAV files, but not .MP3 ones. MCI opens .WAV file, reads its standard header, looks for the compression used and selects the right codec. MCI just does not understand what is the file with .MP3 extension.
But it is possible to have a .WAV file with MP3 compressed data inside, and a such file must be played by MCI.
WAV file has a standard format. WAVEFORMATEX describes its header. In general, you can place any data compressed by any compression algorithm into a wav file.
At first, make sure that you have a MP3 codec which can create WAV files.
Search in the Internet for MP3+WAV+CODEC. See, for example,

<<What you are after is the l3 Mp3 Wave codec (this enables a standard Wave file to contain an Mp3 data stream), this codec is installed with Microsoft Netmeeting>>

Your code works perfectly on my NT, at least, it plays WAV files. But with getch() statement only, see below, i.e. the application must be running to allow MCI to play the file.
Of course, to play mp3, your system must have an appropriate codec installed.
#include <windows.h>
#include <stdio.h>
#include <conio.h>
void main()
{
LPCSTR filename="aaa.wav";
char command[1024];
sprintf(command,"open %s type waveaudio alias mp3",filename);
mciSendString(command,0, 0, 0);
mciSendString("set mp3 time format samples", 0, 0, 0);
mciSendString("play mp3 from 1 to 10000", 0, 0, NULL);
getch();
}
