Suno is the strongest fit here, as it generates original royalty-free music and jingles from text prompts, letting you dial in genre, mood, tempo, and length to match your YouTube content exactly. At $10/mo for the Pro plan it is affordable for regular video production, and tracks created under a paid plan come with commercial use rights. ElevenLabs is worth considering if you also need voiceover or sound effects alongside your music, since it covers a broader audio production workflow. Descript is a better pick if you want an all-in-one tool that handles video editing and audio cleanup in addition to music.
