Given that you have a couple of live versions of FLAC songs, it appears you might want to convert them to MP3 for importing and playing the music in iTunes (Apple Music in Catalina) or iPods. Why? Even though FLAC (Free Lossless Audio Codec) offers CD-or-better-quality music and becomes more popular, it's still not so common to play on the default music player installed on the smartphone (Updated: iPhone or iPad with iOS 11 or above can play FLAC files natively.)
