Without a doubt, Shazam is a great app that I usually use it to search all the melodic songs around me so I can enjoy and explore more masterpiece in the world. However, it’s only available online. That would be so great to have something like a database to store tones of songs in the world so that people can Shazam the song they love OFFLINE but I understand it’s hard to develop a ”GIANT” storage database here. Well... I’ve got a suggestion, will it be possible for people to upload MP3 / Video that they have recorded them when OFFLINE from the photo library? I’ve known that many people have the issue of the limited mobile data, so they might not use Shazam if that song doesn’t important to him/her. However, Shazam is a great tool for people to find their love song and I’m sure music is important to everyone, they are the one who reduce stress. So if that’s possible for people to record video or MP3 offline and send/ upload it to Shazam when they have arrived the WIFI area, I pretty sure it will increase the number of users, it also increases the reputation of your company. Hope it will help you to develop more user-friendly apps to the world. Thank you for reading my comment☺️
