In the first verse, the repetition is clearly intentional. It's a curt observation, meant to be overly simplified. You can't look at only the last two words and judge a rhyme scheme, either. Because the second verse has a pay off and it's the line:
"Or did he hide away from hopes Behind a smile and smoking dope"
This is a pretty good line for an 18 year old, which reads to me as auto-biographical, even though he's referring to another person, he's talking about himself as well.
There's also:
"It makes me wonder when I grow to be that age
Will I be walking down the street begging for your spare change"
That's not only a good rhyme, but an impressive fit syllabically, he really did a good job fitting all those words in to the melody. And then the continuation from this line:
"Or will I grow that old?
Will I still be around? The way I carry on I'll end up Six feet underground And waste away..."
With "away" being a bookend on the "soft a" sound of the pre-chorus. Then "on" falls as a near-rhyme with "around" in the song and it's internal, another impressive fit with the melody.
It's not their best lyrically, but I respect the hell out of any 18 year old who can fit words in to a melody the way he does, and this scheme/lyric is a pretty good one.
That's not true, phrases ending in the same word is a useful and valid technique. The problem with "Whatsername" is the fact that the sounds prior to the last word also don't work together and there is no obvious meaning to the repetition device. With Android, it certainly makes more sense and is also separated by another phrase.
