No man, we are just pointing out that indie is a very broad term. Now, we kinda know what you mean by saying "indie", as the sound probably doesnt fit into what you would typically hear on the radio, such as sonic youth, and perhaps something that really wouldnt fit well into the mainstream listeners library.
What you should have said was perhaps: indie punk, or indie trip hop, or indie hardcore. That sort of thing.
Don't act so flustered at Xenos for pointing out that "its an indie song" gives us little to go on. And by the way, if you are hearing it on commercials, chances are that the band is actually signed, not indie.
