oh - no point learning mandarin through songs IMO. strangely, words like 心 which in school we are taught to pronounce as 'xin' and in dictionary also 'xin' is frequently pronounced as 'shin'.

watch show not so bad la, like watching Singaporean shows - their mandarin really close to ours. watch Channel 19 on Astro (AEC) and you'll get a lot of mandarin shows.
