2015-12-16 10:41:52.291 OC_zuoye_5[650:25353] 歌名-九月

2015-12-16 10:41:52.292 OC_zuoye_5[650:25353] 歌手-许巍

2015-12-16 10:41:52.292 OC_zuoye_5[650:25353] 专辑名-那一年

2015-12-16 10:41:52.292 OC_zuoye_5[650:25353] 我想要离开这浮躁的城市　

2015-12-16 10:41:52.292 OC_zuoye_5[650:25353] 我决定去海边看一看落日　

2015-12-16 10:41:52.293 OC_zuoye_5[650:25353] 让秋日的海风使我清醒　

2015-12-16 10:41:52.293 OC_zuoye_5[650:25353]

2015-12-16 10:41:52.293 OC_zuoye_5[650:25353] 我想到昨天风吹动的夜晚　

2015-12-16 10:41:52.293 OC_zuoye_5[650:25353] 坐在我身边我所有的朋友　

2015-12-16 10:41:52.293 OC_zuoye_5[650:25353] 岁月让我们已变得沉默　

2015-12-16 10:41:52.294 OC_zuoye_5[650:25353] 没有人再会谈论明天　

2015-12-16 10:41:52.294 OC_zuoye_5[650:25353]

2015-12-16 10:41:52.294 OC_zuoye_5[650:25353] 有一些希望和理想　

2015-12-16 10:41:52.294 OC_zuoye_5[650:25353] 总在心里是最美的旋律　

2015-12-16 10:41:52.294 OC_zuoye_5[650:25353] 可如今这真实的生活　

2015-12-16 10:41:52.295 OC_zuoye_5[650:25353] 却演奏着那纷乱的节奏　

2015-12-16 10:41:52.295 OC_zuoye_5[650:25353]

2015-12-16 10:41:52.295 OC_zuoye_5[650:25353] 就好像战争这对手是自己　

2015-12-16 10:41:52.295 OC_zuoye_5[650:25353] 至少我现在已决不会逃避　

2015-12-16 10:41:52.295 OC_zuoye_5[650:25353] 那理想的彼岸也许不存在　

2015-12-16 10:41:52.296 OC_zuoye_5[650:25353] 我依然会走在那旅途上　

2015-12-16 10:41:52.296 OC_zuoye_5[650:25353]

2015-12-16 10:41:52.296 OC_zuoye_5[650:25353] 有一些希望和理想　

2015-12-16 10:41:52.296 OC_zuoye_5[650:25353] 总在心里是最美的旋律　

2015-12-16 10:41:52.296 OC_zuoye_5[650:25353] 可如今这真实的生活　

2015-12-16 10:41:52.297 OC_zuoye_5[650:25353] 却演奏着那纷乱的节奏　

2015-12-16 10:41:52.297 OC_zuoye_5[650:25353] 有一些希望和理想　

2015-12-16 10:41:52.297 OC_zuoye_5[650:25353] 总在心里是最美的旋律　

2015-12-16 10:41:52.297 OC_zuoye_5[650:25353] 到如今它再一次响起　

2015-12-16 10:41:52.298 OC_zuoye_5[650:25353] 又飘荡着在我心里
