Sabrina Setlur-- German rapper. This is her most popular song, but it's all solid. Music video for this one is also cool as fuck, especially for the 90s.
LEA-- great sort of pop/electro singer-songwriter. Actually found out about her because I was at a retreat with her drummer, but fell in love with the record (Vakuum). Definitely worth a listen.
Stoppok-- the OG German rocker. Enough said.
Jan Delay-- singer(?). Kind of in the vein of Peter Fox. Funk/reggae I guess?
Seeed-- reggae. Peter Fox's original group. Pretty fun, not my favorite.
3ergezimmer-- jazz fusion. Who said German music had to have words?
Deichkind-- stupid German party rap. This song translates to "riot and rave."
Ohrbooten-- surprisingly good 90s-esque reggae fusion. Love this one for the lyrics: it's basically an anarcho-communist anthem. (Everything for everyone until everything is everyone's.
I'm gonna take a break for now.
E: OOH, also
