Lyric discussion by FlyingNewb 

This song is about his 'relationship' with hip-hop. A few verses that point that out:

'i gave up my life for you, totally devoted to you' -- We all know how long Eminem has been a rapper. 'Nuff said.

'dont think im loyal, all i do is rap' -- Self-explanatory.

'but in my sickness an addiction, you're addictive as they get' -- Eminem was a recent drug addict, (Hence the album title, 'Recovery') but, this completely stats that rapping is his ultimate addiction.

'go marry someone else and make em famous' -- Kim obviously isn't going to make anyone famous, however being a rap artist will..

'fuck you hip-hop' -- Well, yeah..

And lastly, the chorus:

too late for the other side caught in a change 25 to life too late for the other side caught in a change 25 to life

Eminem's first album titled, 'Slim Shady LP' released in the year(s) of 1997-1999; When he was 25. Hence the lyrics, '25 To Life'. Ironically, it is also the life sentence of imprisonment. Thus being, his life sentence to rapping.

The Slim Shady LP is Eminem's 3rd album after Infinite and Slim Shady EP
