I don't ever have the pressure of making a hit, because I've never had a hit song, per se. The closest thing to a hit song was 'Shiraz,' and it's not your prototypical hit song, with a catchy hook and all this other stuff.
I'm not the type of guy to go so deep with the concept songs, but there's deep thought in everything. Maybe it's not just a repetitive hook telling you what the song is about - you have to use your brain a little bit.
