Hear just the singer
Modern signal processing and machine learning can do some incredible things, one of which is to take a song and isolate just the singer's voice. It's called isolated track vocals and it sounds a bit like an a cappella version of a song. It's a bit weird sometimes, but it lets you hear who's a great singer and who just isn't. Here are some notable vocals I thought you might like.
Freddie Mercury - Queen - We Are The Champions
This man could sing. There are lots of Queen songs that have gone through the isolated track vocals process, but I've just chosen one for you to listen to. As you might expect, Freddie Mercury is outstanding.
Nirvana - Smells Like Teen Spirit
The Beatles - We Can Work It Out
The Clash - London Calling
The singing here isn't as good as on some of the other songs, but there's 100% commitment and passion.
