All just my opinion....
Not bad. Already heard the beat on the samsung commercial. Love what JT did with the intro, adlibs, chorus, but Jay didn't add anything to the song IMO. I would've liked this just as much if it was Tinie Templah or Wale ft. JT. I expect Jay to make more of an impact on a song when he jumps on it. Sounds like a song that was well produced with a well structure chorus and lead ups so a mediocre rapper could still make a hit record. Jay's top tier and I can name like 20 rappers off his radar that woulda killed this. He barely showed up.
Again, not a bad song, actually like this, just sounds like Jay brought none of what makes the song hot to the table. He could be replaced with any rapper on this one and I'd like it just as much. I could just be expecting too much from Jay, i'm a big fan and always expect him to go above and beyond. I did like "open letter".
