From what I've listened to TTT, I can't make heads or tails on what songs should be singles and I'm not sure where I'd place the album yet. 
1. YDO-  

 . Idk how that was chosen as the 2nd single. WMN, Unfaithful, Hard, Shut up and Drive>>>>>>>>>>>YDO
2. 
Where Have You Been- This is the only song that I can say 100% better be a single.
3. 
Talk That Talk- Jay's verse is really good and this gives me strong Hard/Wait Your Turn teas. I know it would do well on Urban stations, I'm not sure about top 40.
4. 
Cockiness- I didn't think I'd like this song cuz I usually hate this style of song like S&M and Peacock but I really like it. I'm afraid that it might be censored but I'd vote for this for a single. It's a fun track that really only Rihanna could do.
5. Birthday Cake- Another song that I heard the preview for and thought it would suck but it's not bad. I'll wait for the full song. 
6. We All Want Love- As usual Rihanna kills it with the ballads. It's a tad bit cheesy but I love the melody of the verses. I get strong Bob Marley teas from this song.
7. Drunk on love- It's good for the most part. I just think that Where have you been did this style of song better than this song.
8. Roc Me Out- Again like Drunk on Love, this song is good but I think Talk that Talk does this style better.
9. Watch N Learn- 

 Bleh.
10. 
Farewell- 

 She always does one ballad as a single and this should be it. 
I bolded the ones that I think should be singles. Obviously, I've yet to hear the bonus tracks and I still need to hear the full of Birthday Cake but so far I like the album, in particular the top half.
