Not sure wher to ask this xd how can i add music to blogs??

I tried a code 

---<Frame WASAAAA DSSDDS width="0" height="0" src="https://ww.youtube.com/embed/7tKkreXOomE//?&amp;;amp;;autoplay=1&amp;;loop=1&AMP;;cdata-poison=1" title="YouTube" frameborder="0" allowfullscreen="allowfullscreen"></iframe>&nbsp;</P--- had to change it a but or else it shows as a video DSDSDS

this one, in the <> section when writing. This worked for me in spacehey and napoleon, but here it doesnt, which i understand xd. But is there an alternative?? another code i should try? something i should change? i just copy pasted this code form a layout so i really dont understand how it works :') 

well just that ig xd. If anyone know pls i would love the help :´)

hi so sorry i royally messed up reading this, you mightve missed the i in iframe? thats my best guess..

Yea the code u'r using is broken but the yt embed codes from spacehey should work over here too. Try this instead: https://justpaste.it/dpit5

Just replace the video id with whatever matches the song u want :P
