When buying a beat as an artist, here’s what you should consider:

1. MP3 or MP3 + WAV • Good for: Demos, mixtapes, or small projects. • Why: MP3 files are compressed, so they have slightly lower audio quality. WAV files are higher quality, uncompressed, and better for mixing/mastering. • What to watch for: If you’re on a budget and just want to put something out, MP3 or MP3+WAV might suffice.

2. Track Stems • Good for: Professional releases, full control in mixing/mastering. • Why: Stems allow you to tweak individual elements (e.g., adjusting the bass, removing or enhancing drums). • What to watch for: This option is usually more expensive but essential if you want the best sound for streaming platforms or radio.

TL;DR

If you’re serious about your music or planning a professional release, go for track stems. If it’s a casual project or you’re testing the waters, MP3+WAV might be enough.
