Any

It depends on what kind of singer I would be.

#1 singles, #1 album, highest grossing tour & critical acclaim xoxo.

#1 World wide

50m album sales

150m single sales in my first era

LOUD teas slayage

Nothing but the best xooxoxoxooox

A platinum single is already a big achievement imo. I mean one million people out there have heard of your song, that's really massive for me.

#5 with a 35k debut week

I"ll go on vacation during my album release week instead of promoting

Just a loyal fanbase.

Marina & The Diamonds type success would be cute

This tbh xooxoxoxooox

I'd be happy with:

Album being top 10
3 singles all being Top 40

I'd want a song and album as big as Baby One More Time.

Xoxoxoxooox

Madonna's first era.

Top 5 debut single in the US. Going #1 in 30 countries including the UK and Europe, Japan and some Asia Countries, Oceania, South Africa.
Debut #2 on the BB 200, going to #1 the next week, #1 on Mediatraffic chart and top 5 around the world.
$100 arena grossing tour WW.
Wins Best Pop Vocal Album at the Grammy, Best Pop Vocal Performance and Song of The Year

I'd be happy with a bubbling under charting single.

I like the thought of it starting off slowly and watching everything build up to a smash second era.

I would like to have Josef Salvat's music and a bit of success.

I want to be a singer, tbh I'd be happy with any personal milestone that I could accomplish. Whether it's a gold selling album or maybe top 40 on the main iTunes chart. The idea is to build off slowly like Shaliyadah88 said.
