Since then, the LP has entered the top five and spawned two more hits in the form of 'Don't Go' and 'Forgiveness'.
With one final track to come from the record - his Ed Sheeran collaboration 'Hush Little Baby' - we called him up to find out how album number two is coming along.
Your new single features Ed Sheeran. Have you been saving the best collaboration for last?
"Honestly, we just put out what we felt was right at the time. We've always wanted to put this record out - we were originally going to release it last year - but it's mad difficult when both artists are in separate campaigns. Everything always clashes. The song has become a fan favourite so I'm pleased to finally get it out there."
Will Ed feature in the video?
"We haven't shot it yet but he's definitely up for it. We've just got to pin him down! He's working so hard at the moment."
He's known for his quirky music videos...
"The song is quite a serious one, so I think we'll be staying away from the quirky stuff this time! A weird video would be awkward for this song, wouldn't it?"
So is this the final single from Black & White?
"This is definitely it now - it's the last one from this record. I'm happy 'Hush' is the final song. To be honest, I haven't been paying much attention to the charts of late, it's all about what feels good and connecting to as many people as possible."
You recently put out a remix of Usher's 'Climax'. We take it you are a fan of the original?
"I really like it, and I thought it would be nice to do something with it. The scene I come from, we just hear a beat we like and nab it and throw it out online. I don't want to get too caught up in the seriousness of the industry - I still want to be able to have fun and freedom with what I do. When I heard that song I wanted to put my own spin on it instantly. It's got that old-but-new feel to it."
The track is produced by Diplo; would you want to work with him?
"He makes good beats, but he's a bit cheeky, so I don't work with Diplo."
Why is he cheeky?
"He tweeted something about me. But he's a cool guy though, I'm sure he means well. I won't be doing anything with him though."
You've been in the studio with Tinie Tempah and Angel recently; does that mean you're working on a new album too?
"I've nearly finished it! I'm also putting out another mixtape called Wretchersize which is just me wretchersizing over some beats. It'll come out before the album."
Be careful you don't run out of Wretch-themed titles...
"Yes, I'm near the end of that now! I'm not sure what else I can use next - please tweet me if you think of one! Wretchribution maybe? I don't know, whatever that means."
What does the new album sound like?
"It sounds like a progression - it's me carrying on from Black & White. I feel like lyrically I've got better, the music has got better with me and the choruses are stronger with it. There's just a better feeling and it's even better this time."
What guest features have you lined up for it?
"I definitely want to work with some more great British acts. There are so many I'm feeling at the moment. The Stooshe girls are cool - I've heard some of their other stuff beyond their first single and it sounds really great. I think they're going to smash it this year."
You're booked for several festivals this year. What do you make of reports that the festival boom is over?
"Festivals are difficult events to organise. There are so many different artists with different needs and styles in one place and one time. I just grit my teeth and get through it. At the same time, they're great events. You can't beat playing to that sort of crowd."
Wretch 32 release 'Hush Little Baby' on May 20. His second studio album follows later this year.
