i could be wrong but i think youd need to specify in the html what element is going to be effected(?) . in inspect element i thiiiink spacehey has names, i belive its located in this part-
<div class="table section"> <div class="inner"> <table class="details-table">
so to push the music player into the general table you might need to specify you want .table section .inner .details-table w specifying you want the first <td> (take what i say w a grain of salt as im use to html css coding on ToyHouse and not SpaceHey)
for me the best way i find out how pple do this stuff is playing around w inspect element or copypasting someones layout code and reading thru it.
EDIT: SORRY I ALSO FORGOT TO SAY!!!! u may also be able to copypaste the music player directly INTO the info table when you edit them
