Re releases?

I never really have heard of re releasing an album before this year. The two latest re releases i have heard of were both platinum albums when they were originally released this year "go figure." Both Eminem and Lady Gaga and there respective labels have decided they will re release there albums with bonus tracks available. Now Eminem promised 2 albums in the same year but has decided to push Relapse 2 back and rerelease his platinum selling Relapse December 21st with 7 bonus tracks along with it. The only problem i have with these re releases is to me it is just another money maker. In this case i dont feel like it is the artists that are doing this it is there labels. Now Eminem owns his own label but it is still under Interscope. Music labels seem to run the artists lives in a sense and will do anything to make an extra dollar. And especially with the growing piracy in music record sales are down heavily. So why not take platinum albums and re release them? Well to me this is not helping the cause its just another way to make money not to help the artist.
