Unfortunately, it won't!
Less is more
Have you ever noticed that some of the biggest hits of all time only have three or four instruments on them? Lots of classic Beatles songs just have a couple simple guitar parts, bass, drums and vocals. Nirvana and Green Day have had monumental hit songs, and neither group is more than a power trio. Even "Billie Jean," one of Michael Jackson's biggest hits, is a simple production with few instruments.
If you have too many parts, melodies and counter-melodies, it can prevent your song from being catchy and memorable. If you try singing two melodies that are played together in a song, it's pretty much impossible... And if you can't do it, neither can your potential fans.
Don't let too many parts get in the way of your song's catchy melody
You should try to limit yourself to one main instrument that will be featured in your production--or at most a lead vocal with a unique melody along with one instrument playing a simple melody that compliments it. If you do more than this, it could distract from the part of the song that you most want people to listen to. Just think back to my post on how minimalist music production can make for maximum hit song potential.
