Companies like Pfeifer Broz. Music, Immediate Music, X-Ray Dog, Music Junkies, etc. are really cracking down on illegal file-sharing. They are very protective about their music and only want it available to trailer-production companies and Hollywood music producers. For some reason they don’t want the general public to have access to their music.
The RIAA has really cracked down recently on said file-sharing and it’s almost impossible to fine working links to download them. They have even gotten sites like Megaupload and rapidshare to side with them and delete all links to their music. I highly doubt you’ll find anyone willing to re-upload any of this type of music because anyone caught with links to their music will practically be dismembered by the music production companies.
This is a serious blow to me as well, but it’s just too dangerous right now to find any of those songs/albums by those artists.
