[arr] ARR Music Database at instrument level

[ajay.ambole]

How about creating a database of all of ARR's music at instrument 
level ? I don't think we have that. A table containing all the songs 
and instruments used in them.
For Example, this table could have columns such as Male voice, Female 
voice, Harmony, Synth, guitar, flute, drums, trumpet, sax ... so on and 
so forth. It's a huge task but I think it could be done.
We can use some online docs such as google docs where everybody can go 
and update it.
Any ideas, comments ?
