Both songs have been played in many TT videos, dont repeat yourself its really boring for viewers. I dont wanna be harsh or anything but most of the video uploaders try to mimic other video tributes using the same and the same songs (requiem for a dream for example, its been in half of the videos out there).
Dont imitate anyone, choose your own music as long as it fits the video. H4ks3lR and bollforte94 for example, they are great video editors and have used many different songs in their videos. Most of the tribute uploaders hear a nice song in a TT video and then make different video but with the same songs playing. Then a new video comes up with a different song and after 2-3 months the same song plays in other videos.
Be creative people, experiment a bit and you will be surprised!
Here is a list of songs that I believe "fit" TT videos as long as you know, how to match image and sound together
Kavinsky - Testarossa Autodrive (Sebastian Remix)
Deadmau5 - Some Chords
Human Beinz - Nobody but me (this song is also featured in the kill bill film @ the black & white scene where Uma Thurman butchers the japanese gang)
Celldweller - Switchback
Clawfinger - Out to get me
Skrillex - First of the Year (Equinox) , you will need some slow motions for this song to match
Skrillex - Bangarang
Korn - Narcissistic Cannibal ft Skrillex and Kill The Noise
Bomfunk MC's - Freestyler, Super Electric, Something Going on
Linkin Park - Breaking the Habit, Lost in the Echo, Session , Faint , Figure 09
