Try searching using pinyin. I find that's successful.

As for searching in chinese, I did one doing an any type search as listed below. Then I changed language & re-opened LW. I did any type search, search for song, search for artist. No. 3 was all from the one search. I had mixed results as far as finding material. You'll notice considerable difference between search 4 & 5 as one was artist search & the other an any type search for artist name. But if you do find some, try browsing that host to see if they have more.
