Which iOS app is best for a turn-based music trivia challenge with a friend?

SongPop Classic is a dedicated music trivia game that excels at asynchronous, turn-based competition. The core gameplay involves challenging a friend or a random opponent to identify artists and song titles from a curated playlist. Each player takes a turn listening to a series of short song clips and racing to select the correct answer from multiple choices. The appeal lies in the back-and-forth nature of the match, which can stretch over hours or days, making it ideal for fitting quick rounds into a busy schedule. The app offers a vast library of playlists categorized by genre, decade, and specific artists, which helps players find common ground or specifically target a friend's musical knowledge. For instance, challenging a colleague to a 90s rock playlist can be a fun, low-stakes social interaction. While the core experience is strong, some long-time users have noted that seasonal interface graphics can sometimes remain static longer than expected, a minor cosmetic quirk. Reviews indicate the community is dedicated, with many reporting they have played daily for years. The app is free to play with optional in-app purchases for additional playlists or power-ups, though the base game offers substantial content.
