Songs that had huge songwriters but flopped?

Basically, an example of when too many cooks spoil the broth.

Passenger from Britney Jean was written by Katy Perry, Sia and Britney herself yet managed to be a pretty forgettable song.

Another example is Cheryl’s Love Made Me Do It which was written by Cheryl’s bandmate Nicola, Natasha Bedingfield, Miranda Cooper (from Xenomania) and freakin’ Kylie Minogue yet it was just crap.

What are some other examples of a song having big songwriters and a great production team but ending up being forgettable?
