I usually tend to pick on the song lyrics after a few listens, especially if its a song I listen to a lot.
Other songs can tend to be parts, but after some listens I'll get the lyrics.
On the other hand, if its a song that I haven't heard in quite a while, I'll usually end up forgetting it......but after listening, I get to remember it, sometimes completely, sometimes only in parts.
Here's the weird part of it, for me that is, I can pick on songs in other languages, yet I absolutely bottom out in my attempts to learn other languages, mainly because of poor focus.
