Hey i have an acquaintance wich i like. Yet she doesn't know it. About a week ago i was at her house and she asked me to transfer music for workout on her ipod; she saw it as her christmas present. She wants music that girls listen to and that can motivate you during workouts.
The problem is that i dont know lots about music...
If you have any recommendations for music, please help me!
(i really want to make her happy!)

I don't know what kind of music she likes, so here's some recommendations. They're not workout music per say, but they're great motivational or energetic songs. I also went with more mainstream songs since they're usually the safest bet lol, but there are some that aren't. You can listen to some first to see if any of them fits.
Woman- Kesha
Thunder - Imagine Dragons
Bonkers* - Dizzee Rascal
Shape of You (BKAYE Remix) - Ed Sheeran
Mi Gente - J Balvin, Willy William
Legend Has It - The Jewels
How to Be a Heartbreaker - Marina and the Diamonds
Oh No! - Marina and the Diamonods
So What - P!nk
Wonder Woman (2017) Theme Song*
It's On Again - Alicia Keys
Young Blood - The Naked and Famous
Hello Bitches* - CL (this is a Korean song. Don't know if she likes Korean music or KPOP, but the song is catchy).
The Bullpen - Dessa
Surrender - Lala Hathaway, Pharrell Williams
Bad Girls - MIA
Renaissance Girls - Oh Land
Stranger Boy - The Weeknd X Stranger Things Remix
Team - Iggy Azalea
You're On* - Madeon (ft Kyan)
* means that some of the songs I'm not too sure about in terms of her taste.
Most of these songs are very girl power type of songs but can also work as workouts, since she said that she wanted something for girls.
Best of luck!

Thank you soooo much!!
