This song is catchy. I can imagine how outstanding it would sound if an exceptionally sounding male singer sang on the track. If you think back to how many people sang ballads in the 70's (or on those infomercials of when music was real), I could imagine someone singing the exact same lyrics in that type of fashion over the same "how to love" instrumental and make it even skyrocket on light rock hits stations and hot ac's as well as some possible play on rhythmics and chr's. I'm sure better singers have already done it on YouTube, although I never thought to check...
As far as Lil Wayne's voice on everything, he does have certain tracks that he sounds very well on. Keri Hilson's "Turnin' me on" is one, and Enrique Iglesias "dirty dancer" is another, to name a few. He also turned out alright on "get money", but mostly due to his rapping skills and the unique way in which he arranged his lyrics in parts of the song.
