naw ill tell you what makes a instant hit song....
-the beat has to be simple, and irritating as fuck... the hook has to be some, "man my 8 yr old cousin coulda came hotter then that"
-you gotta have the "in at the moment" producer, OR rapper cosign for you
-shoot a video wit a bunch of females havin a good time and the dopest car you cant afford
-coin a catch phrase i.e "girrrrl shake that laffy taffy" "errrrrybody in the club get tipsy" "i like the way you do that right thuuuurr" ect ect
-put plenty of 808's in it. make sure you skimp on the beat and lyrics as much as possible, you gotta remember, you want a 2 year old to repeat it, so dont get all extra metaphorical or use more then a 2 sylable word.
now get it to the lable execs, and watch the awkward old white dudes tap there hands and feet to there new found smash hit
there you go, the ingredients to spoon feed the masses and have your own ringtone
