Cover art for Right Now lyrics by TV on the Radio

I think this song could be about one of two things.

1) Not aiming for anything past right now, and being satisfied with casual hookups because long term things aren't really practical and never really last or work out and cause so much pain. So it's better to avoid them and just focus on having a good time in the moment.

OR

2) The key to long term relationships IS focusing on the right now. The lyrics seem to be warning against fixating too much on the past or present, (the people who are locked doors because they're waiting for something "serious" to happen with someone who "wants more", "let go of the souls you lost," ... etc.). So the solution is to let go, and just enjoy life and take things as they come.

Either way, it's a great song.
