have doing sth

楼主是否听错了？

还有楼上的，要是I`m coming 的话后面接着的so numb怎么解释啊？

是I`ve become so numb.

解释一下，就是I have become```````

become became become. become的完成时不变

老外在唱歌的时候啊，有时为了追求音效，可能就会变音，变调，连音，缺省音。
比如这里的`ve在唱的时候就没完全发出来，对于快歌，说唱，hip-pop就更是如此，如果听过bon jovi 的it`s my life这首慢歌就明了了，里面为了追求爆破音变得很厉害的.希望楼主在学歌的时候继续保持严谨的态度，同时也不必执着于标准发音，试想一下唱jay的歌也不必多标准吧~~~~~~我说这么多可是来要分的哦！楼主要追加分啊！

i'm tired of being what you want me to be
feeling so faithless lost under the surface
don't know what you're expecting of me
put under the pressure of walking in your shoes
(caught in the undertow just caught in the undertow)
every step i take is another mistake to you
(caught in the undertow just caught in the undertow)
i've become so numb i can't feel you there
i've become so tired so much more aware
i've becoming this all i want to do
is be more like me and be less like you
can't you see that
