This tumblr seems to say, things that pop up in front of the material you actually want is a turn off. This pattern has two causes: the “call to action” marketing technique, and ignorance of how pop up and pop under techniques ruined older websites.
I’ve always respected the “call to action” (an old version is “Order now!”) but find the internet equivalent (“Like!” “Subscribe!”) pointless since it is likely that a user will ahead know how to do this. Unless it isn’t.
When your lyric is narrative, it won’t always line up to 4 beats and 4 bars, but that’s okay when your rhythm is consistent, the drums are terse, and the narrative has more strength than any other aspect of the song.
