Any good musician careers out there?

Road to Fame! That's the one I use. It's a bit broken inasmuch as not all of its features work as intended, but Sacrificial says it won't hurt your game. I use his Alternative Road to Fame Street Dancer version: VO.5.B2. Sometimes, the concerts and photoshoots will give a 12 hour window instead of a mere 6 hours, which is why I like that one.

It works very well with Get Famous. In fact, under options make certain you set both to enabled. My Sim made it to Global Superstar in 8 Sim days, once. He worked his little Teen fanny off during the summer break I gave them via MCCC.



ETA: Don't forget that handy-dandy drone. Use it when your Sim is out and about trying to make a name for themselves. It's crucial. Also, set up the Simstagram Account and update it. There is a way to have them do it automatically via RTF.
