Lyric Analysis of 'Something in The Way'- Nirvana

In order to help me with my research for choosing my song, I chose to analyse a song by Nirvana. As I believe their music has conventions that interest me in terms of direction.

Underneath the bridge
The tarp has sprung a leak
And the animals I've trapped
Have all become my pets
And I'm living off of grass
And the drippings from the ceiling
But it's okay to eat fish
'Cause they don't have any feelings

Something in the way
Ummmmm
Something in the way, yeah
Ummmmm
Something in the way
Ummmmm
Something in the way, yeah
Ummmmm
Something in the way
Ummmmm
Something in the way, yeah
Ummmmm

Something in the way
Ummmmm

This song is thought to be written by Kurt Cobain in the late 80's describing his experience as a homeless man living under the 'Wishkah Bridge' in Seattle. The song is the final track from Nirvana's 1991 album 'Nevermind.'

The song consists of two verses and two choruses that repeat each other. The tone of the song is extremely sombre as it is describing a depressing time within Cobain's life. Within the verse the lines are fairly standard but are sung slowly so that they can slow down the tempo of the song and keep in timing with the tone presented in the song.

*Underneath the Bridge: Cobain's sleeping spot, whilst homeless
* Living off of Grass: Could either be referring to Cobain's inability to afford really food, or his marijuana use.
*Its okay to eat fish, 'cause they don't have any feelings: Cobain's feelings towards pescatarianism
