Because of its simplicity and flexibility, APEv2 was adopted by the WavPack and OptimFROG formats as their primary tag format. Version 3.99 of the official Monkey's Audio software switched from using APEv1 to APEv2. Media players such as Winamp, foobar2000, MusicBee support reading and writing of APEv2 tags in MP3 files. The tagging string APETAGEX signals the start of an APEv2 record, and the string TAG signals the start of an ID3v1 tag.
