paragraph_text: West's life took a different direction when his mother, Donda West, died of complications from cosmetic surgery involving abdominoplasty and breast reduction in November 2007. Months later, West and fiancée Alexis Phifer ended their engagement and their long-term intermittent relationship, which had begun in 2002. The events profoundly affected West, who set off for his 2008 Glow in the Dark Tour shortly thereafter. Purportedly because his emotions could not be conveyed through rapping, West decided to sing using the voice audio processor Auto-Tune, which would become a central part of his next effort. West had previously experimented with the technology on his debut album The College Dropout for the background vocals of "Jesus Walks" and "Never Let Me Down." Recorded mostly in Honolulu, Hawaii in three weeks, West announced his fourth album, 808s & Heartbreak, at the 2008 MTV Video Music Awards, where he performed its lead single, "Love Lockdown". Music audiences were taken aback by the uncharacteristic production style and the presence of Auto-Tune, which typified the pre-release response to the record.

paragraph_text: Referred to as a ``stoner rap ''by AllMusic's Stephen Thomas Erlewine, the lyrics are mostly nonsensical. The song's chorus, in which Beck sings the lines`` Soy un perdedor / I'm a loser baby, so why do n't you kill me?'', is often interpreted as a parody of Generation X's ``slacker ''culture. Beck has denied the validity of this meaning, instead saying that the chorus is simply about his lack of skill as a rapper. Jon Pareles wrote in The New York Times that`` The sentiment of 'Loser' (...) reflects the twentysomething trademark, a mixture of self - mockery and sardonic defiance'', noting Beck's ``offhand vocal tone and free - associative lyrics ''and comparing his vocals to`` Bob Dylan talk - singing''. After its recording, Beck thought that the song was interesting but unimpressive. He later said, ``The raps and vocals are all first takes. If I'd known the impact it was going to make, I would have put something a little more substantial in it. ''The relationship between Beck and Stephenson soured after the release of`` Loser'' as a single. Stephenson regretted his involvement in creating the song, in particular the ``negative ''lyrics, saying`` I feel bad about it. It's not Beck the person, it's the words. I just wish I could have been more of a positive influence.''
