Warriors VS Worlds Collide

A few things to note:

1. Warriors had a video, Worlds Collide didn't. Though it helped feeling what the song was about, the video itself shouldn't be taken into account, we're talking about the track only.
2. The tracks have different qualities, some may be better in one and some other better in the other one. Comment to nuance your vote.
3. The tracks are what matters, not the singers. Vote for your favorite track.
4. Warriors was the first of its kind, don't forget that it may disturb your judgment.

Edit: For my vote, I'd say I prefer Warriors, not on the melodic level, which is in my feelings equally good in both tracks, but on the message. Warriors makes you follow the player that discovers his talent and struggles to reach the top. Worlds Collide, as the title says, is only about witnessing the clash of the champions, but lacks the story of the rise of those champions. Plus, Warriors puts you in the body of the champion, while Worlds Collide lets you more out of it, like a spectator.
