No, you can't.
No. Rock Band songs only work with Rock Band, and Guitar Hero songs only work with Guitar Hero.
If you have Guitar Hero World Tour, you can make songs on the game!
Depends on the music you like Imo rock band 2 has better songs but that's because rock band 2 has more heavy rock/ metal songs but guitar hero world tour is more on the modern side of songs.
No, but their songs feature in Guitar hero three and rock band.
The Band Hero Guitar works on DJ Hero 1 on the same console as the guitar. The guitar only has parts on a minimal amount of songs, though.
No, there is currently no Jonas Brothers songs on Guitar Hero or Rock Band.
Both Guitar Hero: World Tour,GH5, and Rock Band 2 have song creation tools.
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.
NO
no
Yes the guitar controller for Rock Band will work on Guitar Hero World Tour. Rock Band drums and microphone also work on Guitar Hero World Tour.
it depends i know that guitar hero 2 and 3 are, and rock band 1 and 2 has some older songs. and I'm pretty sure guitar hero 1 does, but if you want classic rock songs don't get guitar hero 4
