yea that's what got my attention with the catchy tunes and simple lyrics which makes it easier to sing along. That's what most people want these days. Us musicians want to play difficult songs with crazy guitar solos all the time but not many people like that all the time. Most people want to listen to simple songs that are catch and with a great beat.
No, that's not at all the case. For example, take into consideration Neutral Milk Hotel (forgive the youtube title, there's nothing about this album that endorses drug use at all)

The songs are incredibly simple, hardly use anything more than four chords, yet it comes off with genuine emotion and great imagery. The lead singer even just exclaims, "I love you Jesus Christ!" after the first song. You don't need complexity to make great music just true, emotional substance.
