my preferred way to play any MP3 files with NAudio is this. I prefer to block the playing thread until Playback stopped with event listeners. Also, for the best compatibility, I use MP3Sharp to load the MP3 file and then pass it to NAudio since NAudio did not come with MP3 codecs.

using NAudio.Wave;
