Drakes "Trophies" is a leftover track from NWTS and was released as a single off Young Money album with no video no promo nothing and killed radios and is still top 3 on Urban radio and sold well on iTunes ... If he would have put this on his album and promoted it it would have smashed
Another example is "All Me" with 2 Chainz & Big Sean .... U see the way drakes impact is huge without videos and promo
