I hope this is true
the title probably isn't the official title yet if this indeed is true , it might be changed into "Super Eurobeat presents Ayu-Ro-Mix IV" or something if it's confirmed by Avex.
and cloudwalking is very right about ayu's trance songs , if you're a trancefan you can't help but to run into them. tho some non-ayu fan trance listeners prefers or hopes for "dub" versions of the songs and some are confused whether AYU is a dj or a group or what lol
but surprisingly many trancefans enjoy Ayu's vocals too
