Pretendiendo comes from the verb pretender, which can mean "to pretend" but also "to try to win over" or "to aspire to". In this song, it carries the latter meaning.
The singer, having moved on from a past relationship, states, "Ahora hay muchos que me están pretendiendo" (Now there are many who are trying to win me over). This word highlights her newfound desirability and independence, making it an engaging choice for a push notification.
Have you ever had an ex who just wouldn't quit calling, even after you've moved on? That's exactly what Agus Padilla is singing about in "Ni Tu Amiga Ni Tu Amante"! She's totally over it, telling her ex, "Me llamas, me buscas, y yo como una tonta caí siempre" [You call me, you look for me, and I, like a fool, always fell for it]. But not anymore! She's found a new life and is making it clear: "No soy tu amiga ni tu amante" [I'm not your friend or your lover].
This song is all about reclaiming your power after a breakup. Agus is done playing games, saying "Conmigo jugaste, ya me convertiste en otra" [You played with me, you already turned me into someone else]. Now she's got other people interested and is ready to go out and "tomarme la noche" [take on the night] and forget about him. It's a fun, empowering anthem for anyone who's finally said goodbye to a past relationship and is ready to live their best life!
