Become the bard or dancer.
*one time change into your ideal version of a guy or girl. You pick only one option.
*Your voice is always the perfect pitch.
*You gain the body and endurance of a top dancer that will never suffer with age.
*You gain a musical sense that would allow you to write songs that would make all the great song composers green with envy.
*You may change your clothing into any design at will and mentally save several of them to be stage costumes for easy access. Like if you're an idol singer and want to wear something cute and flashy while being a horrible tease.
*At will you may generate the sounds of a musical instrument or summon them.
*Your voice gains an enhancing quality to it that draws people in and you may use this to plan subliminal messages in their minds, make them cry from raw emotion, or other things. This can of course be toggled off and on. (This is based off of Aya Asia from nougami neuro so look her up to give the jist at what I was going for with this.)
*You have a very enhanced learning rate when it comes to anything related to song and dance and music. (Like song magic from Ar Tonelico if you happen to go to that universe if you can)
*You age very gracefully and all negative effects of old age are lessened greatly if not outright gone.
*You have the charisma to be a world class Idol.
