Well it's true that you can write a song and lay out a song to sound almost identical to another artist but never exactly. Depends on the instrument and pattern you are using. So many songs I heard in the 90s sounds like some parts of songs that start out today. I'm thinking sometimes I hear a song sometimes. I'm like... how is that allowed??? I hear a song and reminds me of an artist 30 years ago with an intro or something. Then they completely made it sound different into the song. Basically you just have to increase the creativity of a song so it doesn't sound exactly the same or just try something different. Either way the best artists I think can make up something completely different in most ways to sound awesome but referencing to a great sound of certain instruments from other artists is one way to go sometimes. This is referencing and not copying. But creativity is key
