I think a lot of Motion City Soundtrack's songs have a lot of underlining depression, anxiety, and bipolar themes in them. I'm actually kinda stuck in a mixed state right now and they are very soothing to blast loud and listen to. I'll give you some examples...

Delirium:

"There's a voice, there's a voice, there's a voice in my head
It's rather soothing and it tells me I'd be better off dead
But if I beat maybe punch it even kick it away
Then everything will be all rightly

I swim in pharmaceuticals
I swim in pharmaceuticals
The medicine deactivates the things I take
I swim in pharmaceuticals
I swim in pharmaceuticals
The medicine deactivates the things that take me"

I especially like the next part. To me I like to think it's about going off of your meds and into an episode and realizing how badly you actually do need them...

"I didn't know it was hot in the middle
I touched it once then I touched it a second time
'Cause I am that naive
A myriad of bright ideas
I didn't know I'd get caught in the middle
I touched it once and I touched it a second time
'Cause I am that naive
A myriad of bright ideas"

A lifeless ordinary:

I could pull the lyrics from many parts of this song...

"Are we copasetic? Are we behaving now?"

"I always knew I had the answer
But I never understood the question"

"And now we've realigned the edges
I'm doing very well I thank you
All this empathy is starting to wear me down"

"I'll try to work this out
I'll try to get it on
I'll try

I like to tell you that I'm ready
For whatever's coming
But to be honest there's a part of me
That loses control

I think I can figure it out,
But I'm gonna need a little help to get me
Need a little help to get me."

Dissapear:

Just the tempo of this one, how racey and fast it is, gets me everytime I'm in one of those moods...

"Need medication, more medication
Coursing through your interstates
All mad and great, confused and counterfeit
Kamikaze, sear the blood inside me
Guess who's got it figured out
I'll let you in on something secret

I can disappear
Anytime I want to, time I feel you
Shovel through my skin
I am with you til the end"

Even though I think this one is more about alcohol, I really like the last part, plus the tempo, it feels like mania coming on...
