lyric data store and search

hi
  I have many lyrics which are originally binary format.I need to store
them and let users to search them.
1 But i don't know where to store them? using filesystem or database? I
think it is better choosing database because it is easier for me to
implement search function. Am i right?
2 I can store binary data into database,but it is binary looking.when
implement search function or users read lyric,i need readable lyric.so
how to convert those binary data into normal readable text,and then
store them into database?

Thank you!
