Remarks

Check supported formats for info tag support. Some formats can support some sort of "Info tags", but not all. 

libZPlay library implements "ID3 tag" interface to different info tags (VORBIS comment, RIFF Info, ...). So, you can retrieve ID3 informations from different streams (mp3, ogg, flac, wav) because library will convert "format specific tag" to ID3 tag info. 

Note: Use this function if you just need ID3 data and you don't need to play this file. This function only loads ID3 data. There is no checking if this is valid file, wave output isn't open ... This function has no effect on currently open file or stream.
