I totally agree about the music. Download at will, but if you like what you hear, BUY IT. Whether it's Sony/etc or not, pay them the money.
Now with games, I'm f******* sick and tired of game devs not giving us a free demo ahead of purchase. I have NO PROBLEM with buying a game I like, but look at, say, Doom3....I was excited about this game, there was no demo, I was stupid enough to pay 55 bucks the day it came out and the game was almost terrible.
Now had I downloaded it ahead of time, I could have determined if the game was worth my time or not and made that decision whether or not to play.
HL2 = totally worth the money, but again they should have released a demo.
Evil Genius = released a demo, demo was fun....still unsure (the demo left ALOT of things out and ended waaaay to quickly, which left me suspiscious), I D/Led the full version and saw how messy minion management was and how poor the AI was, something that I could not determine in the demo. Hence, I didn't buy it.
