Alek Olsen's "Someday I'll Get It" jumps from No. 19 to No. 1 on the TikTok Billboard Top 50, due to a new TikTok trend of users using the song to remember old pets and passed love ones. G-Eazy's "Lady Killers Part II (Christoph Anderson Remix)" and Madison Beer's "Make You Mine" enter into the TikTok Billboard Top 50.
