How many of these are good tunes/songs and how many of these are good recordings?
Before recorded music a song had to be good song as it was distributed on paper and the first time many people would here it was when they played it themselves. Now we distribute songs as recorded performances
Roman Mars’ show makes a good point here that a lot of popular music is principally about recordings and performances, not about songs and tunes.
The measure of a good tune is whether you can get a good cover version so its suggested that Led Zep performances and recordings are great but their tunes aren’t – thats why Led Zep cover versions are crap. Conversely you can’t play Nirvana’s Lithium and make it sound bad because the song is so good
