No, Guitar Hero 3 has no DLC, if you wanted to put new songs on it you'd have to hack it somehow. The new Guitar Hero: World Tour will have DLC though, you'll be able to download songs onto and play songs from your SD cards (they will probably let you download all the songs from the previous games). If you want more info on Guitar Hero: World Tour for Wii check out the Related Linksbelow.
You can't. You can only download songs in Guitar Hero III for PlayStation 3 and Xbox 360. However, Guitar Hero World Tour, 5, and Warriors of Rock support song downloads for all consoles. But Rock Band has way more downloadable songs, so that might be a better option.
I am not sure but I know you can create songs on guitar hero world tour. I was searching for the same question. I also know that you can download songs already made at the playstation store. (playstation store/addons/disc based games/guitar hero 3)
You have to have internet access at home and connect you xbox. In the market place from the xbox you can search guitar hero 3 downloads
It depends if the Guitar Hero 3 songs were released as DLC on GH: World Tour. There is no way to directly import songs from Guitar Hero 3 onto World Tour.
Probably but you might have to mod your wii, buy gh2, burn and download the songs to a burned disc, and you may have a shot at it workin.
If by guitar hero 4 you mean world tour the answer is yes. go into the xbox live marketplace and look around.
