Went to system/customize/acc/default xml and found beats near the bottom. Changed from false to true and rebooted. Beats now enabled.

Adding beats audio files won't help as the old from m7 wouldn't really work with m8 as the m8 has due to s801 SoC other audio/sound files...it was already tried by the awesome sound mod created Zeroinfinity and he clearly said it won't work...

Well if he cannot do it then I know for sure that I can't.
