The Plain White T's suffer from something me and a friend call the "Lamb-Of-God" syndrom. No, PWT's aren't a metal band, but the two have a similarity. The Lamb-Of-God syndrom is an inside joke; It means an artist has put little variety on the tracks of an album. Whether you find it repetitive or consistent is up to the listener, of course. So don't automatically take it in a negative way.
the Plain White T's are a pop-punk band, with the accent on pop. Musically, this band sounds more like a modern version of The Beatles or The Monkees, rather than being a carbon copy of Green Day or Blink-182.(A little disclaimer before I'm getting barraged by fans of The Beatles or The Monkees; They aren't "classics" like those bands, they simply have more in common musically.)
That said, they have that certain catchiness every pop-punk should have, choruses and hooks that stick in your head are plentiful. I remember after the first time listening to this album, I could already hum along to a couple of songs, which says something, considering I don't have that often.
This is also the bands downside, as you might gradually grow tired off after a few listens. This is made evident by the absence of difference in song structures and sound.(Except the final track.) Verse-chorus-verse is the rule here,while this is common practice in most pop-punk bands, I want to make sure you don't expect the creativity(in terms of song writing) like you'd find in a band like "Gatsbys American Dream".
To describe this band's sound seems almost somewhat excessive, as most people know the trebly sound of power-chord driven pop-punk bands like this one.
However, there are some things worthy to point out.
The bass lines really play a larger part in the music here than is the case with alot of bands in the genre. Some songs seem very bass driven. Not only does it stand out in front of the mix, they don't always follow the guitar lines, providing some nice fills(albeit not technically challenging),
which makes the music a little more interesting.
My second point is about something completely different: Integrity.
Whereas alot of bands like Fall Out Boy or Panic! At The Disco tend to fail in that aspect, It's abundant here. While the lyrics largely focus on broken hearts and relationships, (With the occasional alternative on tracks "Breakdown" and "Lazy Day Afternoon".) It all seems to be from the heart (Just listen to the final track.), and gets to me alot easier than alot of bands that sing about these things. But of course, that isn't for everyone.
