it`s the most easiest music form to make from a musician stand of point, production. good poetry rises the bar but mostly if u compare to music overall it takes less knowledge to make hiphop period. classical music is above everything i mean compositions, orchestra, film scores, symphony. rock/metal + symphony, symphonic rock basically is another hard shit to make, u need musical education to put everything together. some1 would say good progressive trance is another hard shit to make but it`s not that hard, just need a monster pc. as far as vocal goes opera shits on everything and again symphonic rock with full lyric soprano vocals shits on everything. Pop is the easiest genre as the vocals go, rnb is a lot more complex. i don`t know what yall discussing here, anyone who has experience in working with different genres will co sign me.
