A few app suggestions that can be fun and helpful.
You can listen to offline music through Spotify, but remember that you won’t always have a data connection, so download your favourite tunes in advance. You will need a premium subscription to be able to listen to music offline ( €10/month). I think it’s worth it.
If you’re heading for the Caribbean, learn some reggae songs so you can join in on the local Caribbean karaoke shows. A cool Caribbean playlist on Spotify is Caribbean Reggae Beach Groove.
Another option to make all the songs love available to offline listening is through the Amazon Music program (10 euro/months). You can opt for a 30-day trial!
