New feature: music source

[pepak]

I wonder if it would be possible to add "music source" to the listed albums. I am thinking stuff such as:
- lossless - studio recording (e.g. http://vgmdb.net/album/2284)
- lossless - live recording (e.g. http://vgmdb.net/album/10019)
- lossy (16 kHz cutoff) (e.g. http://vgmdb.net/album/16041)
- even more lossy (11 kHz cutoff)
- MIDI render (e.g. http://vgmdb.net/album/2235)
- original sound (e.g. http://vgmdb.net/album/7492)

I guess most albums would have "unknown" value, but where the source is known, it can be very useful (e.g. for the purpose of not hunting for that $200+ CD which is bound to disappoint me due to its low sound quality).
