1. The music industry does not have a significant rise in production costs, like the Videogame industry due to changing technology that isn't produced by simple inflation. In other words, singing into a can is the same thing now as it was 100 years ago. Videogame creation has recently had skyrocketing production costs and vast increases in time taken to create the actual game. Also, it takes relatively little technical training to create music and write songs, so you have a much wider, more competitive, and more eager selection of CHEAP workers than you do in the PC gaming industry. Fact is, it's cheap as hell to make a record, and if it sells half of what it would have due to piracy, it still turns a huge profit. The music industry is a mainstream money pit, and it will never "die."

2. The PC game industy has competition from the console game industry, and the handheld game industry, or more specifically, the PS3, 360, DS, PSP, PS2, and the Wii. The music industry is the music industry. There is no Music Industry 2 for people to flock to when Metallica pisses them off.

3. The music industry has vast encompassing corporations all mutually invested in its success. The PC gaming industry has more vast encompassing corporations, and in fact, and entire console industry, invested in its failure.

I don't think it's a good comparison.

That said, the PC gaming industry isn't dying....at the very least, mindsweeper and Peggle can keep it alive for generations.
